| 摘 要： | ０引言自从上世纪６０年代LiNbO３晶体合成以来，人们对这种材料的兴趣越来越大。它的优良的非线性特征使LiNbO３晶体成为用于光电装置的最好的物质之一，也是信息贮存和全息照相的很好材料。稀土离子可以很容易地掺杂到该晶体中，用频率自动加倍、自猝灭开关和自动密封等方式来发展微激光。在这种意义上，Yb３＋成为主要的激光材料掺杂离子，它的光谱特征在大量体系中已有研究，已经获得了不同基质中的激光犤１～５犦。由于Yb３＋的谱带积分面积较大，所以，Yb３＋已被用作其它稀土离子的敏化剂，用以提高它们的激发效率，如：Yb－Er…

| Abstract: | In C3v point group symmetry, crystal-field energy levels of Yb3+ in LiNbO3 were assigned on the basis of DSCPCF model and PCF model. As compared with the experimental values of crystal-field energy levels, the root-mean-square standard deviation is 16.09cm-1 for the calculation of the DSCPCF model and is 30.30cm-1 for the PCF, respectively. This result shows that the DSCPCF model can fit the experimental values of crystal-field energy levels better than the PCF model. At the same time, Absorption spectra and Emission spectra of Yb3+ in LiNbO3 were analyzed and the peaks that appear in Figures were also assigned reasonably. |
