| Abstract: | With the strong-field scheme and the trigonal bases, by diagonalizing the complete d3 energy matrix in a trigonally distorted cubic-field, the energy spectra and wavefunctions of BeAl2O4:Cr3+ have been calculated. By using the wavefunctions, the g factors of the ground state and the pressure induced shift (PS) of the spectral levels have been evaluated and the calculated results are all in good agreement with the experimental data. The contributions to the rates of pressure induced shift from various parameters are calculated. The physical origins of R1 line have been clearly and quantitatively shown. |
