| 摘 要： | 该文表达了一个研究Yb3+掺杂PbMoO4晶体的光谱和电子顺磁共振谱(EPR)的理论方法. 采用晶体场理论，推导了有关光谱和电子顺磁共振谱的公式. 基于这些理论公式，构建了4f13电子组态在D2d晶体对称下包括Zeeman磁相互作用的14阶能量矩阵. 通过对角化这一能量矩阵，研究了Yb3+掺杂PbMoO4晶体的光谱和电子顺磁共振谱. 所得的理论结果与实验值很好符合. 而且，相关的晶体场参量也在研究中确定.

| Abstract: | A theoretical method was proposed to study the optical and EPR spectra of PbMoO4: Yb3+ crystal.The related formulas of optical and EPR spectra were derived from the crystal-field theory.A 14-order energy matrix of 4f13 electronic configuration in D2d point symmetry was constructed by these formulas.The optical and EPR spectra of PbMoO4: Yb3+ crystal were investigated by diagonalizing the energy matrix.The theoretical results were found to be in good agreement with the experimental values.In addition,the cry... |
