Abstract： Glasscintillators are highly stable detection materials that play a crucial role in medicalimaging，security inspection，and various other applications.They alsoprovide enhanced adaptabilityand detection performance in extreme environments，such as deep-sea，deep underground，deep space，and nuclear reactor.However，the developmentandapplicationofcommerciallavailableGSseriesglassscintilatorsarehinderedbytheirrelativelylow lightyieldand narrowapplicationrange（neutron field），which are insufficient to meet the demands of ΔX -raydetection applications.Consequently，there isan urgent need to developaseriesof glassscintillators with superior ΔX -ray detectionperformancetosatisfytherequirements inX-rayandrelated fields.Inrecentyears，significantprogresshas benmade inthedevelopmentof X-ray-related glassscintilator materials，the explorationof their mechanisms，and theexpansionof theirapplications.However，fewstudies have specificaly focusedon X-raydetectionglass scintillators as adistinct topic，addressng their development and applications.This paper provides a brief overview of the historicaldevelopment，materialclasification，detectionprinciples，detectionparameters，andfabricationprocesses of X-raydetection glass scintilltors.Itparticularly emphasizes thedesign concepts，research advancements，detection performance，andchallenges associated with rare-earth-basedand perovskite-type glassscintilators.Additionally，the paperexplores futuredirectionsandchallnges in X-raydetection glassscintillators，taking into acountcommon issues and the current state of development in this field.

1引言

闪烁体是一种具有能量转换功能的辐射探测材料，可将入射的高能射线（X射线、 γ 射线）和粒子（ ∝ 粒子、β粒子、中子）的电离能转化为低能紫外/可见光，广泛应用于医疗、工业、国防、科学研究和宇宙探索等领域2]。（剩余48741字）
