制备了Er3+-Yb3+共掺硅酸盐玻璃，研究了296-723K温度范围内526 nm和549 nm绿色上转换发光的荧光强度比随温度的变化关系。利用FIR技术得到的绿色上转换发光的最大灵敏度约为0.0033 K-1，温度分辨率约为0.2K。结果表明，Er3+-Yb3+共掺硅酸盐玻璃可以在高温测量中发挥重要作用。(C)2007 Elsevier B.V.保留所有权利。
The Er3+-Yb3+ co-doped silicate glasses have been prepared and the temperature dependence of the fluorescence intensity ratio (FIR) of the green up-conversion emissions about 526 nm and 549 nm in the range of 296-723 K is investigated. The maximum sensitivity and the temperature resolution derived from the FIR technique of the green up-conversion emissions are approximately 0.0033 K-1 and 0.2 K, respectively. The results imply that Er3+-Yb3+ co-doped silicate glass can play an important role in high temperature measurement. (c) 2007 Elsevier B.V. All rights reserved.
