Er3+/Yb3+ 共掺杂锗酸铅玻璃已被用于上转换发光温度传感器。 Er3+的H-2(11/2)→I-4(15/2)和S-4(3/2)→I-4(15/2)跃迁对应的上转换发光光谱随温度变化。测定荧光强度比（FIR）和温度灵敏度。在300-600 K温度范围内，T = 550 K时，最大灵敏度为70 x 10(-4)K(-1)。这表明Er3+/Yb3+共掺杂锗酸铅玻璃有望用于光学温度传感器。 (C) 2016 Elsevier B.V. 保留所有权利。
Er3+/Yb3+ co-doped lead germanate glasses have been examined for up-conversion luminescence temperature sensors. Up-conversion luminescence spectra corresponding to H-2(11/2) -> I-4(15/2) and S-4(3/2) -> I-4(15/2) transitions of Er3+ are changed with temperature. The fluorescence intensity ratio (FIR) and temperature sensitivity were determined. The maximum sensitivity is found to be 70 x 10(-4)K(-1) at T =550 K in the temperature range of 300-600 K. It suggests that Er3+/Yb3+ co-doped lead germanate glass is promising for optical temperature sensors. (C) 2016 Elsevier B.V. All rights reserved.
