Abstract Optimizing charge carrier storage in trap‐controlled halide perovskites poses a significant challenge, particularly due to the varying electronic properties and trap dynamics across temperature range from ≈100 400 K. This dependence affects both efficiency of generation their retention. In this study, substantial advancements performance zirconium stannum are reported through targeted defect engineering. By modulating composition Cs 2 Sn 1‐x Zr x Cl 6 incorporating dopants Cr 3+ , Ga Bi Te 4+ remarkable enhancements X‐ray triggered capacity realized. Notably, ZrCl doped with or exhibits three fold increase 100 300 K, significantly outperforming state‐of‐the‐art BaFBr(I):Eu 2+ red afterglow Y O S:Eu phosphor. The :yTe demonstrates over 40 times greater wide K achieves low detection limit 99.16 nGy for dosimetry applications. Furthermore, :0.03Te exceptional persistent luminescence lasting 14 h at 180 295 research underscores high‐performance capabilities engineered perovskites, paving way application advanced technologies temperatures.

Flexible scintillator screens characterized by high spatial resolution, low cost, and a simple fabrication process are in significant demand for applications medical diagnosis industrial detection. Here, we have demonstrated new Mn2+-doped two-dimensional (2D) Ruddlesden-Popper type perovskite, (4-tert-butylbenzylamine)2PbBr4:Mn, serving as highly efficient candidate. Doping with Mn2+ induces spin-forbidden internal transition (4T1g → 6A1g) that enhances the energy-transfer efficiency from strongly bound excitons of host material to d electrons ions, ultimately leading intense orange-red emission. This photoluminescence quantum yield (4-tert-butylbenzylamine)2PbBr4 (1) decreases its self-absorption. Therefore, at optimal Mn2+-doping concentration, 1:8.4%Mn2+ demonstrates light 21,532 Ph/MeV detection limit 198.19 nGyair s-1, exceeding performance commercial bismuth germanium oxide (BGO) scintillator. Furthermore, combined ultrafine powders poly(dimethylsiloxane) fabricate flexible films. With film thickness mass percentage 1:8.4%Mn2+, films achieve their maximum resolution 17.3 lp mm-1. The above results indicate exceptional scintillation imaging effectively addresses shortcomings current scintillators, thereby providing option family.
