To develop multi‐mode fluorescence thermometer with high performance, Lu2WO6:Er3+,Yb3+ materials were successfully designed and prepared. Under 980 nm excitation, the material can achieve accurate temperature measurement under three models. The above three models are based on different parameters, including two FIR (fluorescence intensity ratio) derived from two thermally coupled energy levels (TCELs) (2H11/2/4S3/2) and two non‐thermally coupled energy levels (NTCELs) (2H11/2/4F9/2), as well as fluorescence lifetime (FL) monitoring of the 2H11/2 energy level transition to the ground state. In the FIR mode of TCELs, maximum relative sensitivity (SR‐max) and minimum temperature resolution are 1.261 %K–1 and 0.237 K, respectively. The repeatability of five‐cycle temperature measurements is above 98.5%. The SR‐max value of FIR (NTCELs) and FL mode reach 0.862 and 0.201 %K−1, respectively. The obtained outcomes suggest that Lu2WO6:Er3+,Yb3+ materials might be considered as promising candidates for three‐mode fluorescence thermometry.

“…This could be crucial in applications where even a small temperature change can be significant. 22 However, Phosphor-based sensors, on the other hand, can be like a high-resolution thermal camera that can show you exactly which areas on your forehead are warmer. They offer more precise temperature readings with better detail.…”

This comprehensive review article discusses the brief history, development, and applications of phosphor-based optical thermometers, which have become increasingly important in various fields due to their ability to measure temperature remotely and with high precision. The article highlights the importance of choosing the suitable phosphor material for a given application, considering factors such as crystal structure and mode of thermometry. It then delves into the structural importance of phosphors, discussing their luminescent properties. The review focuses particularly on fluorescence-based temperature-dependent techniques, including the fluorescence intensity ratio method, which has garnered significant attention due to its straightforward implementation, affordability, and self-referential nature. The article discusses the mathematical formulations underlying this method, including the Boltzmann distribution and the effective lifetime calculation. The review also explores the concept of dual-mode thermometry, which involves the use of multiple luminescent centers to enhance sensitivity and thermal stability. This approach is particularly useful in applications where single-emitter thermometers are vulnerable to variations in excitation intensity or detector stability. The article highlights the advantages, limitations, and future developments of phosphor-based thermometers, including their ability to measure temperature remotely and with high precision.
