为了拓展用于光学测温的上转换发光材料的种类，采用熔体淬冷和热处理的方法合成了一种新型Yb 3 +/Er 3+双掺杂NaSrPO 4纳米微晶玻璃陶瓷。系统研究了其晶体结构形貌和紫外光学性能，并对其发光机理和能量传递过程进行了描述。此外，在980 nm激光下，测量了GC样品在298 K至573 K温度范围内的UC发光与温度变化的关系。利用Er 3+、2 H11/2和4S 3/2的热耦合发射态的发光强度比研究了GC的光温敏性能。在630 °C退火3 h后，样品在298 K时的最大相对灵敏度Sr-max为1.78%K −1，在573 K时的最大绝对灵敏度Sa-max为5.28 × 10− 3 K −1，表明该材料有可能成为光学温度传感器的候选材料。
In order to expand the types of up-conversion (UC) luminescent materials used for optical thermometry, a novel Yb3+/Er3+double doped glass ceramic (GC) containing NaSrPO4nanocrystals was synthetised via melt quenching and heat treatment. The crystal structure morphology and UC optical properties were systematically studied, and the luminescence mechanism and energy transfer process were described. In addition, the relationship between the UC luminescence and temperature change of the GC specimen from 298 K to 573 K was measured under a 980 nm laser. The optical thermo-sensitive performance of GC was studied by the luminescence intensity ratio based on the thermally coupled emission states of Er3+,2H11/2and4S3/2. For the GC sample annealed at 630 °C for 3 h, the maximum relative sensitivitySr-maxat 298 K was 1.78% K−1, the maximum absolute sensitivitySa-maxat 573 K was 5.28 × 10−3K−1, which indicated that the GC materials might be potential candidates for optical temperature sensors.
