摘要

高效温度传感器的发展通过提供快速响应和实现非接触式温度测量，在技术进步中发挥了关键作用。本文利用发光强度比（LIR）技术，研究了Er3+、Yb3+掺杂氟磷酸盐玻璃中Er3+ Stark亚能级的发光温度计。结果表明，在303 ~ 503 K的温度范围内，该玻璃体系具有0.17% K−1的相对灵敏度和良好的重复性，是近红外biii光学温度计的理想选择。

Stokes and Anti-Stokes emission and biological window III (1.53 µm) luminescence thermometry analysis from Stark sublevels in Er3+, Yb3+ -doped fluorophosphate glasses

The development of efficient temperature sensors has played a pivotal role in technological advancement by offering rapid response and enabling non-contact temperature measurement. In this work, a luminescence thermometer from Stark sublevels of Er³⁺ in the biological window III (BWIII) was investigated in Er³⁺, Yb³⁺-doped fluorophosphate glasses, by utilizing the luminescence intensity ratio (LIR) technique. In the range of temperature from 303 K up to 503 K, the results showed that this glass system is a good candidate for an optical thermometer in the near-infrared BWIII with a relative sensitivity of 0.17 % K⁻¹ and good repeatability.
