Description

Technical Field

[0001] This invention relates to the field of high-sensitivity radiation detection technology, and more specifically, to a method for preparing and applying a silver-doped borosilicate glass slide. Background Technology

[0002] Silver-doped phosphate glass, as an important radiation-induced photoluminescence material, has broad application prospects in radiation detection, X-ray imaging, and other fields. Its radiation-induced photoluminescence mechanism is mainly based on the Ag produced by silver ions under radiation. 2+ and Ag 0 The luminescent center stores and retrieves radiation information by capturing electrons and holes.

[0003] However, traditional silver-doped phosphate glasses have significant technical drawbacks. First, their network structure is mainly composed of POP chain or ring structures with low network connectivity. Under high temperature or humid environments, they are prone to structural relaxation, partial depolymerization, and performance degradation. They are also sensitive to chemical media, exhibiting moisture absorption and corrosion problems, thus affecting long-term storage and the stability of photoluminescence performance, which is detrimental to practical applications in radiation monitoring. Second, traditional phosphate glasses have poor mechanical properties, and their fragility limits their application in complex environments.

[0004] To address the aforementioned issues, various improvements have emerged in the prior art. For example, a search reveals that Chinese patent CN118459107A discloses a method for preparing and applying a flexible composite film of silver-doped phosphate glass. This method involves grinding silver-doped phosphate glass into powder, mixing it with a polymer precursor, and then curing the mixture to form a flexible composite film. This addresses the problems of easy hydrolysis of silver-doped phosphate glass in air and the difficulty in preparing ultra-thin, large-size films. However, this technical solution still has the following shortcomings: First, it essentially still uses traditional silver-doped phosphate glass, failing to address the fundamental issues of insufficient thermal stability and chemical durability of phosphate glass from the glass network structure itself. Second, the process of grinding the glass into powder and combining it with the polymer may damage the internal structure of the glass, affecting the uniformity of silver ion distribution and the stability of photoluminescence performance. Third, while the introduction of the polymer improves flexibility, it may adversely affect radiation response sensitivity and luminescence efficiency, and the polymer material may experience aging issues during long-term use.

[0005] To address the shortcomings of existing technologies, this invention proposes a method for preparing silver-doped boron phosphate glass sheets and its applications, solving the aforementioned problems. By introducing boric acid into the glass composition, BOP bridging and BOB structures are formed in the glass network, increasing the crosslinking degree and density at the glass network structure level. This suppresses the decomposition of the phosphate network and the migration of silver ions at high temperatures, significantly improving the thermal stability and chemical durability of the glass. Furthermore, this invention uses a melt-quench method to directly prepare silver-doped boron phosphate glass sheets, avoiding the damage to the glass structure caused by the grinding and composite process, thus maintaining excellent radiation photoluminescence properties. In addition, the introduction of boron, due to its nuclear properties, provides the possibility of neutron trapping, giving the material potential application value in neutron detection and composite radiation monitoring, and improving the response capability to high-dose radiation. Summary of the Invention

[0006] The purpose of this invention is to solve the technical problems mentioned in the background section and to provide a method for preparing silver-doped boron phosphate glass sheets and their applications. This method, by introducing an appropriate amount of boron during high-temperature melting, not only optimizes the cross-linking and compactness of the glass network structure but also maintains its excellent photoluminescence properties for use in radiation dosimeters. Simultaneously, the melt-formed and annealed glass, through mechanical grinding, wire cutting, and polishing, can be prepared into thin sheets with controllable thickness and smooth surfaces, forming a structurally stable and reliable X-ray information storage medium. This medium can expand the radiation measurement dose range and improve the response sensitivity to high-dose radiation. Furthermore, the presence of boron provides potential for neutron detection, making the glass promising for applications in radiation monitoring and neutron imaging.

[0007] The above-mentioned objective of the present invention is achieved as follows: One aspect of the present invention provides a method for preparing a silver-doped borosilicate glass slide, the method comprising the following steps: The raw material powders of each component are thoroughly mixed and placed into a muffle furnace for degassing. The degassed raw material powder is placed in a lifting furnace and fully melted at high temperature; The graphite film is placed in a muffle furnace at a preset temperature for preheating; The molten glass is then poured into a mold to form a shape and placed in a pre-set muffle furnace for annealing. After annealing, the glass is precision ground, polished, and cut to obtain silver-doped borophosphate glass with radioluminescence properties.

[0008] Furthermore, the degassing and melting specifically include the following steps: S1. Weigh out sodium metaphosphate, aluminum phosphate, boric acid and silver chloride according to the stoichiometric ratio, and mix them thoroughly to make the raw materials uniform; S2. The thoroughly mixed raw material powder is loaded into an alumina crucible and placed in a muffle furnace for degassing. S3. Place the graphite film in a muffle furnace at the preset annealing temperature and heat it until it reaches the set preheating temperature. S4. Transfer the degassed corundum crucible containing the raw material powder to the lifting furnace, and clarify and homogenize the raw material under high temperature conditions. S5. After the raw materials have fully melted to the state of molten glass, the preheated graphite mold is removed, and the molten glass is poured into the graphite mold to form a glass blank.

[0009] In the present invention, the response mechanism of the obtained silver-doped phosphate glass after X-ray irradiation can be described by the following reaction equation: A, ; B. (Electron capture); C (hole capture).

[0010] The photoluminescence centers of silver-doped phosphate glasses are Ag2+ and Ag0. An appropriate amount of boron (B) promotes the stability of the internal network structure of the glass and improves its photoluminescence performance. When the P:B ratio is 10:1, it exhibits excellent photoluminescence characteristics.

[0011] Furthermore, the molding and annealing specifically include the following steps: (1) Remove the graphite film from the muffle furnace; (2) Pour the molten glass into a graphite mold and cool it in the air for 2-4 minutes to form it; (3) The slightly cooled and shaped glass is placed in a muffle furnace for annealing and heat preservation to remove internal residual stress.

[0012] Furthermore, in step (3), the heat preservation temperature is 200~850℃, the heat preservation time is 300~1200min, the annealing temperature is 400~700℃, and the annealing time is 300~1200min.

[0013] In this scheme, silver-doped phosphate glass with different Na / Al ratios can be obtained by adjusting the annealing temperature in step (3). However, if the temperature is too high, the stress cannot be well eliminated. Therefore, the above-mentioned annealing temperature is selected.

[0014] Furthermore, the cutting process uses a wire cutting machine to prepare glass sheets with dimensions of 20×20×2 mm.

[0015] Furthermore, in the grinding and polishing process, 200 grit, 600 grit, 2000 grit, 4000 grit, and 8000 grit sandpaper are selected, and then the samples are ground and polished respectively.

[0016] Another aspect of the present invention provides a silver-doped borophosphate glass sheet, which is prepared using the preparation method described above.

[0017] Another aspect of the present invention provides the application of silver-doped borophosphate glass slides in the preparation of radiation monitoring equipment, high spatial resolution X-ray imaging equipment, non-destructive testing equipment, biomedical imaging equipment, or encrypted anti-counterfeiting materials.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention introduces an appropriate amount of boric acid into phosphate glass, forming BOP bridging and BOB structures in the glass network structure, which significantly increases the crosslinking degree and density of the glass network. Compared with the existing technology that only solves the problem of easy hydrolysis by composite polymers, the solution of this invention starts from the glass body structure, fundamentally inhibiting the decomposition of phosphate network and the migration of silver ions, so that the glass sheet itself has excellent thermal stability and chemical durability, and can achieve long-term storage and environmental adaptability without relying on polymer composites, avoiding the potential adverse effects of polymer introduction on radiation response performance.

[0019] 2. This invention achieves effective regulation of the internal structure of Ag-doped glass by precisely controlling the P:B ratio (preferably 10:1) and combining it with an optimized annealing process, thereby enabling silver ions to be uniformly distributed in the glass network and radiating the photoluminescence centers Ag. 2+ and Ag 0 The formation efficiency and stability are significantly improved. For example... Figure 1-4 As shown, the silver-doped borosilicate glass slide prepared by this invention exhibits excellent radioluminescence performance after X-ray irradiation. The decay times of the emission peaks at 450 nm and 650 nm are both in the micrometer range. The recombination rate of the radioluminescence center is relatively fast, and the luminescence intensity shows a good linear response relationship with the radiation dose in the dose range of 0~50 Gy. Its performance is significantly better than that of traditional phosphate glass.

[0020] 3. The introduction of boron in this invention not only improves the structural stability and photoluminescence performance of the glass, but also, due to its high neutron trapping cross section, enables the silver-doped boron phosphate glass sheet prepared in this invention to simultaneously possess the possibility of neutron detection. Compared with the silver-doped phosphate glass composite film in the prior art which is only used for X-ray detection, this invention realizes the combined detection capability of a single material for X-rays and neutrons, providing more technical means for the fields of radiation monitoring and particle detection.

[0021] 4. This invention uses a melt-quench method to directly prepare glass sheets. Through wire cutting and precision grinding and polishing, 20×20×2 mm glass sheets with controllable thickness and smooth surfaces can be obtained, resulting in good product consistency. This avoids the damage to the glass structure and performance instability caused by the grinding and composite process in existing technologies. Furthermore, the process of this invention does not require complex equipment or harsh conditions, making it easy to implement in industrial production. It has high application value and enormous economic potential.

[0022] In summary, this invention successfully prepared a silver-doped borophosphate glass slide with excellent structural stability, environmental stability, radiation photoluminescence performance, and neutron detection potential by introducing boric acid and precisely controlling the P:B ratio and annealing process. This overcomes the technical defects of existing silver-doped phosphate glasses, such as easy hydrolysis, fragility, and unstable performance. It has broad application prospects in fields such as radiation monitoring, high spatial resolution X-ray imaging, non-destructive testing, biomedical imaging, and encryption and anti-counterfeiting.

[0058] The performance tests of Embodiments 1-3 and Comparative Example 1 of the present invention are as follows: 1. Radiation photoluminescence performance test: The glass slides prepared in Examples 1-3 and Comparative Example 1 were subjected to X-ray irradiation treatment with an irradiation dose of 10 Gy, and then their emission spectra were tested using a fluorescence spectrometer.

[0059] like Figure 1 As shown, the silver-doped borophosphate glass prepared in Example 1 exhibits significant emission peaks at 450 nm and 650 nm after X-ray irradiation, indicating its excellent radioluminescence performance. Examples 2 and 3 also show similar radioluminescence performance, but the luminescence intensity is slightly lower than that of Example 1, indicating that the radioluminescence performance is optimal when the P:B ratio is 10:1.

[0060] The boron-free silver-doped phosphate glass slide prepared in Comparative Example 1 also exhibited radiation photoluminescence performance under the same conditions, but its luminescence intensity was significantly lower than that of Examples 1-3, indicating that the introduction of boron helps to improve radiation photoluminescence performance.

[0061] 2. Excitation spectroscopy test: such as Figure 2 As shown, the excitation spectrum of the silver-doped borophosphate glass prepared in Example 1, with a strong emission peak at 650 nm, has a specific excitation peak position, indicating that its luminescence center has a characteristic excitation energy level.

[0062] 3. Decay time test: such as Figure 3 As shown, the decay time of the silver-doped borophosphate glass prepared in Example 1 was tested, and the decay time of its emission peak at 450 nm was measured. Figure 3 a) and the decay time of the emission peak at 650 nm ( Figure 3 b) All are at the micrometer level, indicating that the recombination rate of their radiative photoluminescence centers is relatively fast, which is beneficial for rapid reading of radiation information.

[0063] 4. Radiation dose response test: such as Figure 4As shown, the silver-doped borosilicate glass prepared in Example 1 was subjected to X-ray irradiation treatment with different doses, and the relationship between its luminescence intensity and radiation dose was tested. The results show that within the dose range of 0–50 Gy, the luminescence intensity and radiation dose exhibit a good linear response relationship, indicating that the glass slide is suitable for radiation dose measurement within this dose range.

[0064] 5. Environmental stability test: The silver-doped boron phosphate glass slide prepared in Example 1 and the boron-free silver-doped phosphate glass slide prepared in Comparative Example 1 were placed in an environment with a relative humidity of 90% for 30 days, and then their radiation photoluminescence performance was tested.

[0065] The results showed that the photoluminescence properties of the glass slide in Example 1 did not change significantly before and after storage, while the luminescence intensity of the glass slide in Comparative Example 1 decreased by about 30% after storage, indicating that the introduction of boron significantly improved the environmental stability of the glass.

[0066] 6. Thermal stability test: The silver-doped boron phosphate glass slide prepared in Example 1 and the boron-free silver-doped phosphate glass slide prepared in Comparative Example 1 were heated to 300°C and kept at that temperature for 2 hours, and then their radiation photoluminescence performance was tested.

[0067] The results showed that the photoluminescence properties of the glass slide in Example 1 did not change significantly before and after heat treatment, while the luminescence intensity of the glass slide in Comparative Example 1 decreased by about 25% after heat treatment, indicating that the introduction of boron significantly improved the thermal stability of the glass.

[0068] The test results above show that the silver-doped boron phosphate glass slide prepared in Example 1 exhibits excellent radioluminescence properties after X-ray irradiation, with the optimal performance observed at a P:B ratio of 10:1. The glass slide prepared in Example 1 exhibits a fast recombination rate (microsecond level) at its radioluminescence centers, which is beneficial for rapid readout. The glass slide prepared in Example 1 demonstrates good linear response characteristics within a dose range of 0–50 Gy. Furthermore, the introduction of boron in this invention significantly improves the environmental and thermal stability of the glass, overcoming the technical defects of existing silver-doped phosphate glasses, such as easy hydrolysis and fragility. Moreover, as... Figure 5 As shown (ratio: P:B=9:1; Na:9.02mol% Al:2.25mol% P:12.03mol% O:74.04% Ag:0.03mol% B:2.63mol%), compared to silver-doped phosphate glass, silver-doped borosiphosphate glass has a certain improvement in strength, indicating that it has undergone more complete radiation recombination.

[0069] In summary, the present invention successfully prepared a silver-doped borophosphate glass slide with stable structure, good environmental stability, and excellent radiation photoluminescence performance by precisely controlling the P:B ratio and annealing process. It can be widely used in fields such as high-sensitivity radiation monitoring, X-ray imaging, non-destructive testing, biomedical imaging, and encryption and anti-counterfeiting, and has significant creative and practical value.
