采用熔融急冷法制备了Er 3 +/Yb 3+共掺碲锌铌（TZNb）玻璃，并将其用于点式全光纤温度传感器。采用差热分析和拉曼光谱研究了玻璃的热稳定性和网络结构特性。高的玻璃化转变温度有利于拓宽工作温度范围。实验研究了绿色上转换发光的荧光强度比（FIR）在276 ~ 363 K范围内随环境温度的变化关系，在363 K时，其最大温度灵敏度为95 × 10−4 K−1。该点温度传感器具有较强的绿色上转换发光、较宽的测温范围和较高的灵敏度，是一种很有应用前景的光学温度传感器件。
Er3+/Yb3+ codoped tellurite-zinc-niobium (TZNb) glass was prepared by the melt-quenching method and used for the construction of a point all-fiber temperature sensor. The glass thermal stability and network structural properties were studied by differential thermal analysis and Raman spectrum, respectively. High glass transition temperature is beneficial to widen the working temperature range. The dependence of fluorescence intensity ratio (FIR) of green upconversion emissions on the surrounding temperature from 276 to 363 K was experimentally investigated and the maximum temperature sensitivity is 95 × 10−4 K−1 at 363 K. Strong green upconversion emission, broad temperature measurement range and high sensitivity indicate this point temperature sensor is a promising optical device for application on optical temperature sensing.
