In this study, CaF₂–ZnO–P₂O₅–CaO–SiO₂ system glass ceramics containing Ca₅(PO₄)₃F nanocrystals were prepared via melting and crystallization, and their structure, up-conversion luminescence properties and energy transfer were investigated. Owing to the different temperature dependences of the three emitting bands at 523, 547 and 659 nm, dual-mode temperature measurement can be realized according to the employed fluorescence intensity ratio technology. Using thermal-coupled energy levels, the maximum relative sensitivity (S_r-max) and absolute sensitivity (S_a-max) were found to be 1.71% K^-1 and 0.69% K^-1, respectively. Moreover, the maximum relative sensitivity (S_r-max) and absolute sensitivity (Sa-max) were found to be 2.19% K^-1 and 0.11% K^-1, respectively, based on the nonthermal coupled energy levels. This shows that fluoroapatite transparent glass ceramics have latent application prospects in the optical temperature measurement field.

本研究采用熔融结晶法制备了含有Ca ₅ (PO ₄ ) ₃ F纳米晶的CaF ₂ –ZnO–P ₂ O ₅ –CaO–SiO ₂系玻璃陶瓷，并对其结构、上转换发光特性和能量转移进行了研究。被调查。由于 523、547 和 659 nm 三个发射波段的温度依赖性不同，因此可以根据采用的荧光强度比技术实现双模温度测量。使用热耦合能级，最大相对灵敏度 ( S _r-max ) 和绝对灵敏度 ( S _a-max) 分别为 1.71% K ^-1和 0.69% K ^-1。此外，基于非热耦合能级，发现最大相对灵敏度 (S _r-max ) 和绝对灵敏度 (Sa-max) 分别为 2.19% K ^-1和 0.11% K ^-1。这说明氟磷灰石透明玻璃陶瓷在光学测温领域具有潜在的应用前景。
