Embodiment 1
[0026] (1) Synthesis of CdS seeds: TOPO (3.299g), ODPA (0.603g), and CdO (0.100g) were mixed in a 50ml flask, heated to 150°C and placed in vacuum for 1h. The solution was heated to 320°C under the protection of nitrogen, and the CdO dissolved solution became colorless and transparent. (TMS)2S (0.170 g), TBP (3 g) were injected when the temperature reached 320°C. The heating mantle was removed after the reaction had proceeded for 7 min. The synthesized nanocrystals were precipitated in methanol, washed repeatedly by its redissolution in toluene and increasing methanol precipitation, and finally the nanocrystals were dissolved in TOP. (2) Synthesis of CdS nanorods: TOPO (3g), ODPA (0.29g), HPA (0.08g) and CdO (0.093g) were placed in a 50ml flask together, heated to 150°C and placed in vacuum for 1h. Under the protection of nitrogen, the solution was heated to above 300°C, and the CdO dissolved solution became colorless and transparent. When the temperature reached 350°C, 1.5g...

[0028] Steps (1) (2) The method for synthesizing CdS nanorods, the structure, composition and optical properties of the nanorods are all the same as in Example 1. (3) Assembling CdS nanorods: the prepared electrodes are first assembled. Clean them ultrasonically with acetone, ethanol, and deionized water for 15 minutes, and dry them under vacuum. Depend on Figure 6 The scanning electron microscope (SEM) photo of the middle electrode shows that the electrode spacing is 100 nanometers. CdS nanorods synthesized by the colloidal chemical seed growth method were dissolved in toluene to make a concentration of 10 -7 M CdS nanorods in toluene solution. Next, the prepared electrode chip was immersed in the above solution, and the assembly voltage was 5V, the frequency was 80Hz, and the capture time was 120s by using the method of dielectrophoresis (DEP). After assembly, the chip was gently rinsed with deionized water and dried in a vacuum oven. (4) Photoelectric performance test...

CdS nanorods synthesized by the colloidal chemical seed growth method were dissolved in toluene to make a concentration of 10 -7 M CdS nanorods in toluene solution. Next, the prepared electrode chip was immersed in the above solution, and the method of dielectrophoresis (DEP) was adopted, the assembly voltage was 5V, the frequency was 90Hz, and the capture time was 60s. After assembly, the chip was gently rinsed with deionized water and dried in a vacuum oven. (4) Photoelectric performance t...
