Preparation and Research Progress of Glass Scintillators for X-ray Imaging

Abstract Scintillators have numerous applications in the fields of precision detection of high-energy physics nu clear physics research medical diagnosis industrial flaw detection and national defense security monitoring.How ever traditional single crystal scintillators are difficult to realize large-scale preparation due to their complex process es high costs and limited volume size.In recent years glass scintillators have stood out due to their highly mature production processes low costs good efficient luminescence and excellent plasticity.This paper elaborates on the luminescence mechanism of glass scintillators and enumerates key parameters for evaluating their scintillation perfor mance.Based on their components and structural characteristics glass scintillators are mainly classified into oxide glass scintillators halide glass scintillators and micro/nano-crystalline composite glass scintillators.This review fo cuses on the overview of the latest research results and development trend of glass scintillator for X -ray and summa rizes the high-density glass scintillator.Finally the future development trend of glass scintillator for X-ray is summa rized and outlooked.
