Abstract X‐ray imaging technology has been widely used in the fields of environmental monitoring, safety inspection, nondestructive examination, space exploration, and medical diagnosis, among which scintillation materials play a vital role indirectly converting to visible photons. Here, zero‐dimensional organic–inorganic hybrid halide C 50 H 44 P 2 SbCl 5 crystal is prepared via facile antisolvent precipitation method at room temperature. The single displays strong yellow broadband emission centered 592 nm with near‐unity photoluminescence quantum yield 98.42%. Importantly, crystals show great stability irradiation stability. Radioluminescence characterization indicates that exhibit good linear response dose rates along an excellent light 460 photons MeV −1 , surpassing commercial inorganic LuAG:Ce scintillator. spatial resolution ‐based scintillating screen determined be 8.2 lp mm . In conjunction polymer thin film, feature halides offers exciting opportunities for achieving high‐quality flexible imaging.
