摘要
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.
