Er/Yb 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 K 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.
采用熔融淬火法制备了铒/镱共掺杂碲酸盐-锌-铌（TZNb）玻璃，并将其用于构建点式全光纤温度传感器。分别通过差示热分析和拉曼光谱研究了玻璃的热稳定性和网络结构性质。高玻璃化转变温度有利于拓宽工作温度范围。实验研究了276至363 K范围内绿色上转换发射的荧光强度比（FIR）对周围温度的依赖性，在363 K时最大温度灵敏度为95×10 K。强烈的绿色上转换发射、较宽的温度测量范围和高灵敏度表明该点式温度传感器是一种很有前途的用于光学温度传感的光学器件。
