Abstract:Scintillators have numerous applications in the fields of precision detection of high-energy physics,nuclearphysics research,medical diagnosis,industrial flawdetection,and national defense security monitoring.However,traditionalsinglecrystalscintilatorsaredificult torealizelarge-scalepreparationduetotheircomplexprocesses,high costs,and limited volume size.Inrecent years,glass scintilators havestoodoutdueto their highly mature production processs,lowcosts,good eficient luminescence,and excellent plasticity.This paper elaborates on he luminescence mechanismof glasscintillators and enumerates key parameters for evaluatingtheir scintilltion performance.Basedon their components and structural characteristics,glassscintilators are mainly clasified into oxide glasscintilators,halideglasssintillators,and micro/nano-crystallinecompositeglassscintilltors.Thisreviewfocuses ontheoverview of thelatest research resultsand development trendof glasscintillatorfor X-ray,and summarizesthehigh-density glassscintillator.Finally,thefuturedevelopmenttrendofglass scintillatorforX-rayissummarized and outlooked.

1引言

闪烁体作为一种能将入射的高能射线(X射线、γ射线)或辐射粒子(热中子、 ∝ 射线、β射线)转化为紫外或可见光的发光材料,通过与光电探测器(如各种光电二极管、光电倍增管、电荷元件等)耦合可实现对高能粒子和电离辐射的探测,在核物理、生物医学影像、工业无损探伤、地质勘探和国防安全等领域有着广泛的应用需求。(剩余35754字)
