Given that optical thermometers are widely used due to their unique advantages, this study aims address critical challenges in existing technologies, such as insufficient sensitivity, limited temperature measurement ranges, and poor signal recognition capabilities. Herein, we develop a thermometer based on the fluorescence intensity ratio (FIR) of Sb-doped Cs2NaInCl6 (Cs2NaInCl6:Sb). As increases from 203 323 K, thermally induced transition triplet singlet self-trapped excitons (STEs) leads enhanced 455 nm photoluminescence (PL) STE recombination. Thus, FIR monotonically depends temperature, allowing for sensing with high absolute sensitivity (SA) 0.0575 K-1 maximum relative (SR) 1.005% K-1. We demonstrate spatial distribution can be measured by mapping PL spectra, even transparent medium screening target. Furthermore, blue emissive Cs2NaInCl6:Sb is mixed yellow Cs2AgInCl6:Sb thermal quenching feature. The color mixture dramatically enabling user-friendly colorimetric sensing. Therefore, two operational modes proposed meet various practical application demands.
