| 摘要: 运用配位场理论方法获得了Ho3+离子低自旋4f95d组态的谱项和J-光谱多重态, 根据电偶极跃迁选律合理地解析了LiYF4晶体中Ho3+离子在真空紫外区(120～160 nm)的吸收光谱, 4个主要的吸收峰分别被归属为从基态(5I8)到Ho3+离子的低自旋4f95d组态的自旋允许跃迁。 |

| Abstract: Spectral terms and J-spectral multiplet of low-spin 4f95d configuration of Ho3+ were obtained with the method of ligand field theory. According to the selection rules for dipole transitions, the absorption spectra of Ho3+ doped in LiYF4 in vacuum ultraviolet region (120~160 nm) of the spectrum were theoretically interpreted by applying the crystal field model, and the four main bands were assigned to the spin-allowed transitions from the ground state (5I8) to J-spectral multiplet of low-spin 4f95d configuration of Ho3+ ion. |
