摘要： 计算了Ｅｒ３＋掺杂的氟氧化物玻璃材料ＭＦＴ的Ｊ－Ｏ参数，进而获得了一些能级间跃 迁的跃迁几率、分支比、及寿命等数据．测量了室温下Ｅｒ３＋的较强的两个绿色发射2H11/2、4S3/2→4I15/2及红色发射４Ｆ９／２→４Ｉ１５／２的激发光谱，观测2H11/2、4S3/2→4I15/2跃迁 荧光强度随着温度的变化，测量了室温下这两个跃迁衰减曲线，计算了这两个能级的无辐射跃 迁几率及量子效率．

关键词: MFT玻璃, J-O理论, 量子效率, 无辐射跃迁

Abstract: The optical transitions intensity parameters of Er3+ in MFT glass were calculated by using the J-O theory. The transition
probabilities, branching ratios and lifetimes of Er3+ ion were obtained. The excitation spectra were measured monitored at intense
green of 2H11/2, 4S3/2→4I15/2 transitions and red fluorescence of 4F9/2→4I15/2 transition
of Er3+ ion. The fluorescence intensity variation with temperature for 2H11/2, 4S3/2→4I15/2 transitions was observed.
The fluorescence decay of 2H11/2, 4S3/2→4I15/2 transitions was measured and the quantum efficiency and non-radiative transition rates were calculated.

Key words: MFT glass, J-O theory, quantum efficiency, non-radiative transition
