摘要
运用配位场理论方法获得了Pr3+离子4f15d1组态的光谱项和光谱支项,根据电偶极跃迁选律合理地解析了CaF2和Cs2NaYCl6晶体中Pr3+离子的真空紫外跃迁光谱,2个主要谱峰被归属为Pr3+离子的基态与4f15d1组态3 H4和3 G3之间的跃迁,这对于研究稀土离子的真空紫外光谱具有一定的理论指导作用.
Spectroscopic terms and spectroscopic branched terms of the 4f15d1 configuration of Pr3＋ were obtained with the method of ligand field theory.According to the selection rules for electric dipole transitions,the VUV transition spectra of Pr3＋ doped in CaF2 and Cs2NaYCl6 crystals were theoretically interpreted,and the two main bands were assigned to the transitions between the ground state and spectroscopic branched terms（3H4 and 3G3） of the 4f15d1 configuration of Pr3＋ion,it has theoretic direction function to research VUV spectrum of rare earth ion at some extent.
