| 摘 要： | 研究了氧化物玻璃中Ｅｕ３＋离子的敏化发光。结果表明，硅酸盐玻璃中Ｂｉ３＋向Ｅｕ３＋离子产生共振能量转移而对Ｅｕ３＋发光起敏化作用；磷酸盐玻璃中，Ｐｒ３＋，Ｓｍ３＋对Ｅｕ３＋离子产生特征激发敏化发光，提出了声子支助的共振能量转移模型，解释了Ｅｕ３＋的敏化发光。

| Abstract: | Sensitized luminescences of Eu 3+ in oxide glasses are studied. The results show that Eu 3+ luminescence is sensitized by Bi 3+ in silicate glass on the basis of the resonant energy transfer, Eu 3+ luminescences are sensitized by Pr 3+ and Sm 3+ in phosphate glasses. The model of the resonant energy transfer by the absorption and emission of lower energy phonon is established, and the reason for sensitized luminescence of Eu 3+ is explained. |
