| 摘 要： | 本文首次在稀土离子晶场光谱拟合中引进了唐敖庆等人的张量算符方法,从而获得了激光和上转换材料LiYF4:Pr3+对应于晶场群链(R3?Td?D2d?S4)的能级分裂链,逐级晶场参量值和逐级近似波函数。这就为分析其有关空间电荷分布构形,讨论其光谱强度和其它光学、磁学、热力学性质等提供了逐级近似的依据。

| Abstract: | In this paper. Tang's tensor operator method is applied to a fitting calculation of crystal-field energy levels of the rare earth ions. The splitting chain of energy levels of LiYF4: Pr3+,crystal-field parameters and approximate wave functions cor-reoponding to the crystal-field group chain R3?Td?D2d?S4 are ohtoined. These results can he used to analyse various prohlems, such as space charge distribution, spectral line intensity and other optical, magnetic and thermodynamic properties in cases with different approximate symmetry.
