Description

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.
