摘　　要：制备出单掺Eu3+离子的氟氧化物玻璃陶瓷系列样品,利用Eu3+离子作为荧光探针,通过热处理前后Eu3+离子发射光谱中电偶极子跃迁与磁偶极子跃迁强度比值的变化表征在玻璃材料中微晶是否形成,分析了Eu3+离子荧光发射谱中电偶极子跃迁与晶体场对称性的关系,进一步表征了稀土离子所处微晶晶格场的变化.In oxyfluoride glass-ceramics, the fluoride nanocrystals doped with rare earth ions were dispersed in an oxide network. The emission of Eu^3＋ has high sensitivity to different crystal field and is suitable for microstructure research in neoceramic glass. Different oxyfluoride glass ceramics doped with Eu^3＋ were prepared. The variation of the emission spectra of Eu^3＋ in different glass ceramics confirms the applicability of Eu^3＋ ions in neoceramic glass as microprobe before and after heat treatment.
