Existing optical thermometers are faced with the challenges of high sensitivity limited to a very narrow high temperature range, while also lacking low temperature sensing performance. A new linear up-conversion (UC) optical thermometer with high sensitivity over a wide temperature range was reported here. The introduction of Cr3+ optimized the red-green (R/G) ratio and improved the temperature sensing characteristics of Ho3+-doped tungstate materials. Notably, as a temperature-related parameter, the R/G emission intensity ratio of Ho3
