The urgency for cost-effective, high-resolution, flexible X-ray imaging detectors is generating great demand for scintillators with low-temperature processability, high scintillation yield, and negligible afterglow. X-ray imaging materials are currently dominated by inorganic scintillators in the form of rigid films and bulk crystals, which have inherent limitations including high-temperature, complex synthesis, and considerable challenges toward advanced nonplanar imaging. Here, high-performance and flexible X-ray scintillators based on novel zero-dimensional (0D) (BTPP)2MnX4 (BTPP = enzyltriphenylphosphonium, X = Cl, Br) halides are reported. They emit bright green light originating from the 4T1-6A1 transition of Mn2+ under X-ray excitation. In particular, (BTPP)2MnBr4 single crystals exhibit excellent air- and radiation-stability, a high scintillation yield of 53 000 photons MeV−1, a low detection limit of 89.9 nGyair s−1.
