非稀土激活的无机玻璃闪烁体研究进展OA

Scintillators,serving as core conversion materials for high-energy radiation detection and imaging,play an indispensable role in medical imaging,security inspection,industrial non-destructive testing,and high-energy physics.Although traditional rare-earth ion-doped scintillators(e.g.,Tb3+,Eu3+)exhibit excellent performance,they face challenges such as high raw material costs and narrow emission bands.Non-rare-earth-activated inorganic glass scintillators have emerged as a research focus for the next generation of radiation detection materials,owing to their wide range of activators,broadband emission,and strong environmental adaptability.This article systematical-ly reviews the luminescence mechanisms and recent advancements in such materials,with an in-depth discussion of major material systems,including transition metal ion doping(e.g.,Mn2+,Cu+,Sn2+),oxide nanocrystal-embedded glass,and novel perovskite glass(lead-based,manganese-based,copper-based).Innovative strategies in sensitized energy transfer,in-situ crystallization control,halogen coordination engineering,and fiber array fabrication are de-tailed,along with significant improvements in key performance indicators such as light yield(up to 425％of BGO),spatial resolution,and thermal quenching resistance(63％intensity retention at 573 K).The review also highlights existing challenges,including the gap between achieved and theoretical light yields,the trade-off between high crys-tallization rates and optical homogeneity,insufficient long-term radiation stability,and the need for lead-free alterna-tives.Future research should focus on multi-scale structural modulation,defect engineering,lead-free design,and device integration technologies to facilitate the practical application of non-rare-earth glass scintillators in advanced medical imaging,industrial non-destructive testing,and extreme environment detection.
