Low‐dimensional copper halides with perovskite–analogue structure are a rapidly growing material family for light‐emitting and X‐ray screening devices. Among them Cs 3 Cu 2 I 5 exhibits exceptional optoelectronic properties (large Stokes shift, high emission yield), due to the strong confinement effect of its 0D structure. However, radioluminescence response energetic ions has only marginally been explored heavy fully ignored detrimental luminescence quenching. Herein, scintillation thin layers in wide range atomic mass ionization density, as well electrons using Compton‐coincidence technique, is investigated. The photon yield, linearity, energy resolution investigated key parameters spectroscopic performance. Different semiempirical quenching models used better understand relationship between yield density. capability polycrystalline films found on par that single‐crystal CsI:Tl detect ions. This makes easily processable thin‐film an attractive addition scintillator landscape.

Abstract Manganese halides are one of the most potential candidates for large‐area flat‐panel detection owing to their biological safety and all‐solution preparation. However, reducing photon scattering enhancing efficient luminescence scintillator screens remains a challenge due uncontrollable crystallization serious nonradiative recombination. Herein, an organic cation modulation is reported control process enhance properties manganese halides. Given industrial requirements X‐ray detector, A 2 MnBr 4 screen (900 cm ) with excellent uniformity blade‐coated at 60 °C. Theoretical calculations in situ measurements reveal that cations larger steric hindrance can slow down screen, thus neatening crystal arrangement scattering. Moreover, also endow material higher exciton binding energy, which beneficial restraining Therefore, BPP (BPP = C 25 H 22 P + exhibits superior spatial resolution (>20 lp mm −1 ultra‐low limit (< 250 nGy air s ). This first time used screens, it believes this study will provide some guidance development high‐performance halide scintillators.
