[0043] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0044] In an exemplary embodiment, Figure 1 As shown, a method for chiral modification of quantum dots is provided. This embodiment uses the method applied to a terminal as an example, wherein the terminal may be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices may be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, projection devices, etc. Portable wearable devices may be smart watches, smart bracelets, head-mounted devices, etc. The head-mounted devices may be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc. It is understandable that the method may also be applied to servers, and may also be applied to systems including terminals and servers, and may be implemented through the interaction between the terminals and servers. In this embodiment, the method includes the following steps S10-S20. Among them:

[0045] Step S10, obtaining quantum dot information and processing requirement information of the quantum dots to be modified.

[0046] Wherein, quantum dots may refer to nanoscale semiconductor materials, and their diameter is usually between 1 and 10 nanometers. The quantum dots to be modified may refer to quantum dots that need to be surface-modified in order to expand the scope of application and improve performance. The quantum dots to be modified may be at least one of cadmium sulfide quantum dots, cadmium selenide quantum dots, copper sulfide quantum dots and gallium sulfide quantum dots.

[0047] In one embodiment, the quantum dots to be modified include cadmium sulfide quantum dots; the preset performance conditions include preset optoelectronic device performance conditions, wherein the preset optoelectronic device performance conditions include at least one of preset optical performance conditions and preset photostability conditions.

[0048] Among them, cadmium sulfide quantum dots can refer to semiconductor nanoparticles composed of cadmium and selenium elements and with a size within the nanoscale range. Cadmium sulfide quantum dots have a high fluorescence quantum yield and can produce strong fluorescence signals at low concentrations. They are suitable for high-sensitivity photoelectric detection. Because cadmium sulfide quantum dots have excellent photoelectric conversion efficiency and carrier mobility, they are suitable for photoelectric devices such as solar cells, light-emitting diodes, and photodetectors. In addition, by changing the size of cadmium sulfide quantum dots, precise control of their emission wavelength can be achieved, covering the entire spectral range from ultraviolet to visible light. However, cadmium sulfide quantum dots lack high selectivity when detecting and responding to specific light signals, and are easily interfered by other light signals, affecting the performance of the device. They are also prone to degradation under environmental conditions such as high temperature, high humidity and strong light, resulting in performance degradation and shortened life. Chiral modification of the quantum dots to be modified can overcome the above defects, give them chiral optical activity, enable them to respond to specific light signals with high selectivity, and improve the performance and stability of photoelectric devices.

[0049] The performance of an optoelectronic device may refer to various key parameters and characteristics of an optoelectronic device under specific working conditions, which determine the efficiency, stability and reliability of the optoelectronic device. The performance of an optoelectronic device may include at least one of the optical properties of the modified target chiral quantum dots and the optoelectronic properties of an optoelectronic device provided with the target chiral quantum dots, wherein the optical properties include at least one of circular dichroism and circularly polarized luminescence, fluorescence quantum yield, etc., and the optoelectronic properties include at least one of luminous efficiency, photoelectric conversion efficiency, responsiveness, quantum efficiency, stability and efficiency, etc.

[0050] The chiral modification processing scheme of the quantum dots to be modified may refer to the process of introducing chiral molecules or chiral structures into the surface or interior of the quantum dots to be modified by chemical methods, thereby giving them chiral optical activity. The chiral modification processing scheme of the quantum dots to be modified contains a large amount of information, and illustratively, may include at least one of a chiral modification formula and a synthesis path. The chiral modification formula may include at least one of the type, ratio, and properties of the synthetic raw materials, and the synthetic raw materials may include the quantum dots to be modified and the chiral molecules, and may also include processing aids such as solvents and catalysts required in the chiral modification process. The synthesis path may include at least one of the synthesis steps, the equipment used in each synthesis step, and the process parameters of each synthesis step.

[0051] Quantum dot information may refer to information related to quantum dots to be modified, and may include at least one of quantum dot identification information, quantum dot property information, and quantum dot modification knowledge information. Quantum dot identification information may include the name and number of the quantum dot. Quantum dot property information may refer to information about quantum dots that have been determined in the chiral modification process currently required for prediction, including at least one of quantum dot size information, quantum dot shape information, and quantum dot component information. Quantum dot property information may be determined based on actual processing requirements. For example, since the size of quantum dots can directly affect their band gap width and quantum efficiency, the specific size or size range of the quantum dots to be modified can be directly determined when the requirements for band gap width and quantum efficiency are known in actual application scenarios.

[0052] The processing requirement information may refer to other information in the chiral modification processing scheme of the quantum dots to be modified, in addition to the quantum dot information, which may be determined based on actual processing requirements and actual conditions.

[0053] In an exemplary embodiment, the processing requirement information includes at least one of chiral molecule requirement information, synthesis path information and performance testing conditions; wherein the chiral molecule requirement information includes at least one of chiral molecule configuration information, chiral molecule reactivity information and chiral molecule binding mode information; the synthesis path information includes at least one of synthesis equipment, synthesis steps, environmental conditions for each synthesis step, operation time for each synthesis step, etc.; the performance testing conditions include at least one of performance testing temperature conditions, performance testing solvent conditions and performance testing acidity and alkalinity conditions.

[0054] Among them, the chiral molecule requirement information may refer to the relevant information of the chiral molecule required for chiral modification of the quantum dots to be modified that can be determined before the prediction, and may include at least one of the chiral molecule configuration information, chiral molecule reactivity information and chiral molecule binding mode information, wherein the chiral molecule binding mode may refer to the binding mode between the chiral molecule and the copper sulfide quantum dot, such as coordination binding, covalent bond binding, adsorption, etc. The synthesis path information may refer to the process parameters in the synthesis process of the chiral molecule and the quantum dots to be modified that can be determined before the prediction, and may include at least one of the synthesis equipment, synthesis steps, environmental conditions of each synthesis step, and operation time of each synthesis step. The performance detection conditions may refer to the environmental conditions of the target chiral quantum dots obtained after modification in the application process that can be determined before the prediction. Based on the environmental conditions of the target chiral quantum dots in the application process, the environmental conditions for the performance detection of the target chiral quantum dots can be determined. By unifying the performance detection conditions, the difference between the performance detection results and the prediction results can be made to more accurately reflect the prediction effect of the model.

[0055] For example, when a user has a need to design a chiral modification processing plan, the user can send quantum dot information of the quantum dots to be modified and processing requirement information to the terminal through information input operation; the terminal can receive the quantum dot information and processing requirement information sent by the user.

[0056] Step S20, based on the quantum dot information and the processing requirement information, predict the chiral modification process of the quantum dots to be modified, and obtain the target chiral modification result that meets the preset performance conditions; wherein the target chiral modification result is used to guide the chiral modification processing of the quantum dots to be modified to obtain the target chiral quantum dots.

[0057] The chiral modification process may refer to the process of chemically modifying or transforming the quantum dots to be modified using chiral molecules at the molecular level. The performance condition may refer to the conditions that the performance of the target chiral quantum dots obtained after modification needs to meet, for example, the performance condition may be that the optical performance of the target chiral quantum dots is the highest, or that the optoelectronic performance of the optoelectronic device provided with the target chiral quantum dots is higher, etc.

[0058] As an example, in the case where the performance conditions include multiple conditions, the multiple performance conditions can be comprehensively evaluated to obtain comprehensive conditions, and the various properties of the chiral quantum dots can be comprehensively scored to obtain a comprehensive score. The target chiral modification result can be determined by comparing the comprehensive score and the comprehensive conditions. As another example, the priorities of multiple performance conditions can also be pre-set. When determining the target chiral modification result, they are compared in order of priority. For example, if the priority is from high to low as the preset optical performance conditions and the preset photostability conditions, the optical performance conditions are the five with the highest optical performance, and the photostability conditions are the three with the highest photostability, then the five with the highest optical performance can be selected from a large number of chiral modification results, and then the three with the highest photostability can be selected from these five chiral modification results as the final target chiral modification result.

[0059] The chiral modification result may refer to all or part of the chiral modification processing scheme that can realize the chiral modification of the quantum dots to be modified. For example, the chiral modification result may be a complete chiral modification processing scheme including quantum dot information and processing requirement information, or it may be a predicted and determined part of the chiral modification processing scheme, or it may be a user-specified output part of the chiral modification processing scheme. The specific content may be determined based on actual conditions, and this embodiment does not impose any limitation on this.

[0060] In some feasible embodiments, the chiral modification results may include: weighing 5 grams of pre-prepared cadmium sulfide quantum dots and dispersing them in 100 milliliters of deionized water, then adding 1 milliliter of 50 mg / mL L-tartaric acid solution, and stirring the reaction at 60 degrees Celsius for 2 hours; obtaining pure chiral quantum dots by centrifugation and washing, and the chiral quantum dots are chiral cadmium sulfide-tartaric acid complexes.

[0061] In some feasible embodiments, the target chiral modification result may include at least one of a chiral modification formula and a synthesis path. After determining the chiral modification formula and the synthesis path, the corresponding synthesis raw materials can be obtained according to the chiral modification formula, and then the synthesis raw materials are processed according to the synthesis path to perform chiral modification on the quantum dots to be modified, thereby obtaining the modified target chiral quantum dots.

[0062] In some feasible implementations, the processing requirement information may also include part of the chiral modification formula and synthesis path. For example, if the user wants to modify the quantum dots to be modified with tartaric acid, tartaric acid can be used as one of the processing requirement information, and then the chiral type and synthesis path of tartaric acid, etc., and other information in the chiral modification processing scheme other than the processing requirement information are predicted. For another example, if the user's current processing hardware conditions are limited and he wants to process based on the current processing hardware conditions, and the processing hardware conditions will restrict the synthesis path, then the current processing hardware conditions can be used as one of the processing requirement information, and the model can be used to determine the chiral modification formula and synthesis path that can be used under the current processing hardware conditions.

[0063] The target chiral modification result may refer to a chiral modification result that meets a preset performance condition. The target chiral modification result may be used to guide the chiral modification processing of quantum dots to be modified, and to process target chiral quantum dots with better performance prediction results for optoelectronic devices.

[0064] Illustratively, after obtaining quantum dot information and processing requirement information, a feasible chiral modification process of the quantum dots to be modified can be inferred based on the quantum dot information and processing requirement information through model algorithms, digital simulations, logical reasoning programs, etc., to obtain multiple chiral modification results and performance prediction results corresponding to each chiral modification result, and then, based on the performance prediction results corresponding to each chiral modification result, one or more chiral modification results that meet preset performance conditions are selected from the various chiral modification results as target chiral modification results.

[0065] As an example, after obtaining the target chiral modification result, relevant personnel or processing equipment can perform chiral modification on the quantum dots to be modified based on the target chiral modification result to obtain the target chiral quantum dots.

[0066] In the above-mentioned quantum dot chiral modification processing method, by obtaining the quantum dot information and processing requirement information of the quantum dot to be modified, and then based on the quantum dot information and processing requirement information, predicting the chiral modification process of the quantum dot to be modified, and obtaining the target chiral modification result that meets the preset performance conditions; wherein, the target chiral modification result is used to guide the chiral modification processing of the quantum dot to be modified, and obtain the target chiral quantum dot, realizing the chiral modification processing scheme design process for the quantum dot to be modified and the actual processing requirements, and the relevant personnel or processing equipment performs chiral modification processing on the quantum dot to be modified based on the target chiral modification result, and can process the target chiral quantum dot that meets the actual processing requirements and the preset performance conditions. Compared with the traditional laboratory design method, the present application can automatically simulate and predict the corresponding performance of multiple chiral modification processing schemes in a shorter time, so as to more quickly screen out the target chiral modification results that meet the preset performance conditions, effectively save manpower and material resources, shorten the design time of the chiral modification processing scheme, and thus effectively reduce the manpower cost, resource cost and time cost of chiral modification of the quantum dot to be modified.

[0067] In an exemplary embodiment, the quantum dots to be modified include cadmium sulfide quantum dots; the preset performance conditions include preset optoelectronic device performance conditions, wherein the preset optoelectronic device performance conditions include at least one of preset optical performance conditions and preset photostability conditions; the prediction process of the chiral modification process of the quantum dots to be modified is performed by a chiral modification large model, and the chiral modification large model includes a prediction layer and an output layer; based on the quantum dot information and the processing requirement information, the chiral modification process of the quantum dots to be modified is predicted to obtain the target chiral modification result that meets the preset performance conditions, including steps S21 to S22. Wherein:

[0068] Step S21, predicting the chiral modification process of the quantum dots to be modified based on the quantum dot information and the processing requirement information through the prediction layer, and obtaining multiple chiral modification results and the optoelectronic device performance prediction results corresponding to each chiral modification result.

[0069] The chiral modification large model may refer to a large-scale computing model used to predict and design chiral modification processing schemes, and the large-scale computing model may be a deep learning model or a machine learning model, etc. The chiral modification large model may be trained and optimized in advance. As an example, a large amount of real quantum dot modification experimental data may be obtained in advance from various databases and laboratories, and the large model to be trained may be trained using these quantum dot modification experimental data to obtain a trained chiral modification large model.

[0070] As an example, a chiral modification large model can be obtained by fine-tuning a pre-trained large model. The fine-tuning process of the pre-trained large model includes: obtaining the pre-trained large model and the labeled data of the quantum dots to be modified, as well as the performance labels of the optoelectronic devices corresponding to the labeled data of the quantum dots to be modified; using the pre-trained large model, based on the labeled data of the quantum dots to be modified, predicting the chiral modification process of the quantum dots to be modified, and obtaining the performance training prediction results; calculating the model loss based on the difference between the performance training prediction results and the performance labels of the optoelectronic devices, and iteratively optimizing the pre-trained large model based on the model loss to obtain the chiral modification large model.

[0071] The prediction layer is used to infer the chiral modification process of the quantum dots to be modified with different chiral molecules using different synthesis routes, as well as to infer the optoelectronic device performance of the chiral quantum dots modified by each chiral modification process.

[0072] Exemplarily, after obtaining the quantum dot information and the processing requirement information, the quantum dot information and the processing requirement information can be input into the chiral modification large model, and through the prediction layer of the chiral modification large model, based on the quantum dot information and the processing requirement information, the feasible chiral modification process of the quantum dot to be modified is inferred to obtain multiple chiral modification results, each chiral modification result at least includes the modified chiral quantum dot, and the performance prediction result of the optoelectronic device corresponding to each modified chiral quantum dot. It can be understood that the chiral quantum dots after modification are different for different chiral molecules or different synthesis paths. Even if the chiral quantum dots modified by the same chiral molecule using different synthesis paths are different in specific structure and performance, due to the different synthesis paths, there are still differences. Therefore, the chiral quantum dots corresponding to each chiral modification result are different, and the performance prediction results of the optoelectronic device may also be different.

[0073] Step S22, through the output layer, based on the performance prediction results of each optoelectronic device, select a target chiral modification result that meets the preset optoelectronic device performance conditions from each chiral modification result.

[0074] Among them, the output layer is used to screen and output the target chiral modification results that meet the preset optoelectronic device performance conditions.

[0075] Exemplarily, after obtaining multiple chiral modification results and the optoelectronic device performance prediction results corresponding to each chiral modification result, the output layer can be used to select one or more chiral modification results that meet the preset optoelectronic device performance conditions from the various chiral modification results based on the optoelectronic device performance prediction results corresponding to each chiral modification result and the preset optoelectronic device performance conditions as the target chiral modification results.

[0076] In some feasible embodiments, the number of target chiral modification results can be multiple. The chiral modification large model is mainly used to infer feasible chiral modification processes, and predict the optoelectronic device performance of the modified chiral quantum dots, so as to screen out a more optimal chiral modification processing scheme, that is, it is mainly used for the initial screening of chiral modification processing schemes, reducing the number of experiments in the initial screening stage, but before mass production, it is still necessary to verify by experiment. Therefore, the target chiral modification results with better prediction results of multiple optoelectronic device performance prediction results can be screened out, and then verified in combination with experiments, and further selected in combination with the actual situation and verification results in the experimental verification process. In this way, by combining the large model with the experiment, not only can the large model be used to reduce the number of experiments in the initial screening stage, effectively reducing labor costs, resource costs and time costs, but also the quality and reliability of the chiral modification can be ensured by experimental verification.

[0077] In an exemplary embodiment, the prediction process of the chiral modification process of the quantum dots to be modified is performed by a chiral modification macromodel, such as Figure 2 As shown, based on the quantum dot information and the processing requirement information, the chiral modification process of the quantum dots to be modified is predicted, and after obtaining the target chiral modification result that meets the preset performance conditions, steps S30 to S40 are also included. Among them:

[0078] Step S30, obtaining the performance prediction results and performance measurement results of the target chiral quantum dots, wherein the performance prediction results are predicted by the chiral modification macromodel based on the quantum dot information and the processing requirement information, and the performance measurement results are obtained by performing performance detection on the processed target chiral quantum dots by a performance detection device.

[0079] Among them, the performance prediction result can refer to the performance information of the target chiral quantum dots predicted by the chiral modification macromodel, which can be predicted by the chiral modification macromodel based on the quantum dot information and processing requirement information. The performance measured result can refer to the performance information obtained by testing the target chiral quantum dots actually processed through experiments, which can be obtained by relevant personnel or processing equipment actually processing the target chiral quantum dots based on the target chiral modification results, and then testing the performance of the actually processed target chiral quantum dots.

[0080] Exemplarily, after the chiral modification large model outputs the target chiral modification result, relevant personnel or processing equipment actually processes the target chiral quantum dots based on the target chiral modification result, and then performs performance testing on the actually processed target chiral quantum dots to obtain the actual performance measurement results; simultaneously, the performance prediction results calculated by the chiral modification large model during the prediction process can be obtained.

[0081] Step S40, optimizing the chiral modification large model according to the performance prediction results and the performance measurement results.

[0082] Exemplarily, by comparing the difference between the performance prediction results and the actual performance measured results, the model prediction loss can be calculated based on the difference between the performance prediction results and the actual performance measured results, and then the chiral modification large model can be optimized based on the model prediction loss through back propagation.

[0083] It is understandable that the chiral modification large model in the actual application process has been optimized, and further optimization in the actual application process can be performed after each prediction, or can be performed regularly at intervals. For example, the performance prediction results and performance measurement results are collected every week or every month, and the data generated in these application processes are used to further optimize the chiral modification large model on a weekly or monthly basis.

[0084] In this embodiment, by collecting data and performing further optimization during the application of the large chiral modification model, the defect of insufficient data in the training stage can be compensated, and the model performance and the accuracy of chiral modification can be further improved.

[0085] In an exemplary embodiment, obtaining the measured performance results of the target chiral quantum dots includes steps S31 to S32.

[0086] Step S31, according to the target chiral modification result, controlling the chiral modification processing device to perform chiral modification processing on the quantum dots to be modified to obtain the target chiral quantum dots.

[0087] Herein, the chiral modification processing device may refer to a device capable of performing chiral modification processing.

[0088] For example, after the chiral modification macromodel outputs the target chiral modification result, the chiral modification processing device can be controlled according to the target chiral modification result to perform chiral modification processing on the quantum dots to be modified to obtain the target chiral quantum dots.

[0089] As an example, a chiral modification processing device may include a weighing module, a stirring module, a centrifugal module and a washing module; the target chiral modification result includes a chiral modification formula and a synthesis path, and the synthesis path includes stirring process parameters, centrifugal process parameters and washing process parameters; according to the target chiral modification result, the chiral modification processing device is controlled to perform chiral modification processing on the quantum dots to be modified to obtain target chiral quantum dots, including: according to the chiral modification formula, controlling the weighing module to weigh the synthetic raw materials required for the chiral modification processing, and adding them to the container of the stirring module, and then, according to the stirring process parameters, controlling the stirring module to stir the synthetic raw materials, and transferring the stirred materials to the centrifugal module, and then, according to the centrifugal process parameters, controlling the centrifugal module to centrifugally separate the materials, and then, according to the washing process parameters, controlling the washing module to wash the centrifuged materials, and the washed materials are centrifuged again through the centrifugal module to obtain target chiral quantum dots.

[0090] Step S32, controlling the performance detection device to perform performance detection on the target chiral quantum dots to obtain the performance measurement results of the target chiral quantum dots.

[0091] Herein, the performance detection device may refer to a device capable of performing performance detection.

[0092] For example, after the target chiral quantum dots are processed, the target chiral quantum dots can be transferred to a performance detection device, and the performance detection device can be controlled to perform performance detection on the target chiral quantum dots to obtain actual performance measurement results of the target chiral quantum dots.

[0093] As an example, the quantum dots to be modified include cadmium sulfide quantum dots; the performance detection device may include an optical device preparation module and a detection module, and the detection module may include at least one of a light source, a spectrometer, a quantum efficiency tester, etc.; the performance detection device is controlled to detect the predicted performance results of the optoelectronic device of the target chiral quantum dots to obtain the actual performance results of the target chiral quantum dots, including: controlling the optical device preparation module to deposit the target chiral quantum dots onto the substrate of the optical device; and then controlling the detection module to detect the optical performance and photostability of the optical device deposited with the target chiral quantum dots.

[0094] In this embodiment, through the automated control of the chiral modification processing device and the performance detection device, the automated verification of the target chiral modification result can be achieved, and the verification result can be used to optimize the chiral modification macromodel.
