通过实验测量了Ｐｒ３＋在氟化物玻璃中的光学吸收，根据Ｊｕｄｄ－Ｏｆｅｌｔ理论计算了Ｐｒ３＋离子的振子强度、辐射跃迁几率、分支比等光谱参数。并通过对能级的拟合，给出了Ｐｒ３＋在玻璃介质中的Ｓｌａｔｅｒ参数、自旋－轨道耦合和电子组态相互作用参数。
The optical absorption of Pr3 + in fluoride glass was measured experimentally and the spectral parameters such as oscillator strength, radiation transition probability and branching ratio of Pr3 + ions were calculated according to Judd-Ofelt theory. And by fitting the energy level, the parameters of Slater parameter, spin-orbit coupling and electronic configuration interaction of Pr3 + in glass are given.
