Recent Progress of Zero-dimensional Hybrid Antimony-based Metal Halide Materials in X-ray Detection

Abstract The development of new scintillator materials with both high luminescence performance and environmental friendliness is urgently needed for the high-sensitivity and low-dose development of X-ray detection and imaging technologies.Zero-dimensional antimony-based metal halides exhibit high photoluminescence quantum yield (PLQY) large Stokes shifts and excellent structural tunability by virtue of their unique 5s 2 electronic configurations and self-trapped excitons (STEs) radiation mechanisms which make them promising candidates for lead-free scintillators.In this paper we systematically review the luminescence mechanism and design strategy of zero-dimensional antimony-based hybrid metal halides and their research progress in X-ray detection and imaging.It is shown that such materials exhibit excellent light yield and low detection limit under X -ray excitation while high spatial resolution imaging is achieved in X-ray imaging applications.Finally we point out the main challenges currently faced by zero-dimensional hybridised antimony-based metal halides and provide an outlook on their future directions.Key words zero-dimensional hybrid antimony-based metal halides X-ray detection and imaging scintillators current status of research
