| 摘 要： | 主要从理论上分析了LiYF4 ∶Nd晶体中Nd3+离子的 4f3→ 4f2 5d跃迁光谱 ,提出了 4f2 5d组态谱项的组合方案 ,从而可以标记 4f2 5d组态的各个能级。据跃迁选律 ,说明了Nd3+离子的基态向 4f2 5d组态的跃迁。理论分析与实验结果符合很好。

| Abstract: | In theory, 4f3→4f25d transition spectrum of Nd 3+ ion in LiYF_4 single crystals was studied and the combination scheme of spectral terms for 4f25d configuration were brought forward. Therefore, the energy levels of 4f25d configuration could be labeled. According to the selection rules for dipole transitions, the transitions from ground state to the Stark components of 4f25d configuration were explained. Theoretical analysis is consistent with the experimental result. |
