摘要：

In recent years, low dimensional organic–inorganic hybrid copper(I) halides have a great potential in the fields of photoelectric and radiation detection applications due to their high fluorescence quantum efficiency, excellent stability, and low-cost processing feasibility. We prepared a zero dimensional (0D) (TPA)CuI2 (TPA=tetrapropylammonium, C12H28N+) single crystal scintillator by a simple solution evaporation method, and investigate its optical and scintillation properties. (TPA)CuI2 crystal has a high thermal stability and an air stability. Under UV excitation, it exhibits an ultra-broadband white light emission with a full width at half-maximum (FWHM) of 291 nm and a photoluminescence quantum yield (PLQY) of 62%. Under X-ray excitation, it has an intense radioluminescence, a low afterglow and a decent detection limit, which can be regarded as a novel X-ray scintillator. © 2023 Chinese Ceramic Society.
