本文对两种氟铟酸盐玻璃样品进行了荧光强度比测量。在125 ~ 425 K的温度范围内，研究了掺Er ~（3+）0.1 mol%氟铟酸盐玻璃在523 nm和545 nm处的绿色发光，在425 K时的最大灵敏度为0.0028 K ~（-1）。在掺杂0.1mol%Ho ~（3+）的样品中，分析了545 nm和750 nm的发射随温度变化的关系，在59 K得到最大灵敏度为0.0036 K ~（-1）。采用两种氟铟酸盐玻璃样品，在406 nm和473 nm两种低成本半导体激光器泵浦下，可以很容易地覆盖从20 K到425 K的较宽温度范围。(C)2011爱思唯尔有限公司版权所有。
The fluorescence intensity ratio technique for two fluoroindate glass samples has been carried out. The green emissions at 523 nm and at 545 nm in a 0.1 mol% of Er3+ doped fluoroindate glass was studied in a wide range of temperature from 125 K to 425 K with a maximum sensitivity of 0.0028 K-1 for 425 K. In a sample doped with 0.1 mol% of Ho3+ the emissions at 545 nm and at 750 nm were analyzed as a function of temperature from 20K to 300 K obtaining a maximum sensitivity of 0.0036 K-1 at 59K. Using both fluoroindate glass samples a wide temperature range from 20K to 425 K is easily covered pumping with two low-cost diode laser at 406 nm and 473 nm. (C) 2011 Elsevier Ltd.
