Unveiling Mechanism of Temperature-Dependent Self-Trapped Exciton Emission in 1D Hybrid Organic–Inorganic Tin Halide for Advanced Thermography
Lead-free hybrid metal halide phosphors/crystals showing self-trapped exciton (STE) emission have been recently explored for thermography due to the strong temperature dependence of their photoluminescence (PL) lifetime (τ). However, realizing high-spatial-resolution thermography using polycrystalline powders or crystals presents a challenge. Moreover, the underlying mechanism of temperature-depen
