Abstract Scintillators, essential for applications in nuclear medicine, radiation detection, and industrial inspection, convert high‐energy into visible light. Manganese (Mn)‐based inorganic–organic hybrid materials are distinguished by their thermal stability, mechanical strength, flexibility. However, the effects of temperature on Mn(II)‐based scintillators have not been clearly analyzed, making elucidation temperature‐dependent luminescence mechanisms particularly important. A notable advancement is synthesis Mn‐ 1 nanocrystals (NCs) using methyltriphenylphosphonium chloride (mtppCl) MnCl₂. These NCs exhibit distinctive photoluminescence luminescence: intensity decreases from 77 to 150 K but paradoxically increases at higher temperatures due anomalous exciton behavior [MnCl₄] 2 ⁻ tetrahedra.

Additionally, they show exceptional stability under continuous irradiation can be incorporated flexible scintillating film with resolution 11.3 lp/mm an MTF 0.2. The current study has further refined mechanism optimizes properties wider range applications.

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.
