| 摘 要： | 制备了几种不同化学成分的掺Ｐｒ３＋氟化物玻璃，测定了玻璃的吸收光谱和荧光光谱。根据Ｊｕｄｄ－Ｏｆｅｌｔ理论模型研究了玻璃成分对Ｐｒ３＋发光性质的影响。结果表明，Ｐｒ３＋在氟锆酸盐玻璃中的发光性能优于氟铝酸盐和氟磷酸盐玻璃中的发光性能，随着ＮａＦ被ＮａＣｌ的取代，发光性能进一步改善。

| Abstract: | Several Pr3+-doped fluoride glasses with different chemical comPOsitions were prepared. The absorption and fluorescence spectra of the glasses were measured, and some fluorescent properties of glass were calculated by using the Judd-Ofelt theoretical model. It is shown that the fluorescence properties of Pr3+ ion in fluorizirconate glasses are better than those in fluoroaluminate and fluoophosphate glasses, and the radiative transition probabilityand the stimulated emission cross section increase. ItS fluorescence bandwidth decreases with the increased substitution of NaCl for NaF in the fluorozirconate glasses. |
