Abstract

0D organic metal halide hybrids (OMHHs) have recently emerged as a new generation of scintillation materials, due to their high luminescence quantum efficiency, sensitivity, stability, and cost-effectiveness. While numerous 0D OMHH scintillators have been developed to date, most of them are based on solution grown single crystals that require time-consuming synthesis and are limited in size. Here, high-performance X-ray scintillators based on facile solution processed 0D OMHH amorphous films are reported for the first time. By reacting triphenyl(9-phenyl-9H-carbazol-3-yl) phosphonium bromide (TPPcarzBr) with manganese bromide (MnBr2), 0D (TPPcarz) MnBr amorphous films can be prepared via solution processing with mild thermal annealing, which exhibits green photoluminescence with an emission maximum approximate to 517 nm and a photoluminescence quantum efficiency of approximate to 87%. The X-ray scintillation of 0D (TPPcarz) MnBr amorphous films is characterized to exhibit a light yield of 44600 photon MeV-1 and an outstanding linearity with a low limit of detection of 32.42 nGyairs-1 over a wide range of X-ray dose rates. The versatile processability of 0D (TPPcarz) MnBr is illustrated with remarkable recyclability, high cost-effectiveness, and scalability for large-scale production. By taking advantage of the amorphous nature of newly designed OMHHs, the approach opens up new opportunities for developing high-performance, solution-processable scintillators.
