Abstract Lead‐free metal halide perovskites and derivatives microcrystals (MCs) have become emerging candidates for X‐ray scintillation imaging applications. However, the luminescent properties of micrometric crystals need to be further improved, development flexible screens utilizing large‐scale MCs remains a significant challenge. Here, all‐inorganic manganese (Mn)‐based perovskite CsMnCl 3 are reported by room‐temperature solution‐synthesized co‐precipitation method. Introducing an amount Group IIB divalent cations (i.e., Zn Cd in this work) into greatly increases photoluminescence quantum yield (PLQY) from 48.2% 92.3% :1.5% (82.5% :1%Cd MCs). The feature excellent performance achieve low detection limit 22.53 nGy air s −1 . Furthermore, solvent engineering adding n‐hexane mixture doped polydimethylsiloxane (PDMS) assists fabricating 100 cm 2 large‐area uniform screens. As result, spatial resolution :1.5%Zn@PDMS achieves 7.6 line pairs (lp) mm , which is among best values @PDMS In addition, high‐resolution applications non‐planar objects achieved. work offers promising approach develop high‐performance based on large‐size imaging.
