| 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. |
