| 中文摘要 | By means of both the theory for pressure-induced shifts (PS) of energy spectra and the theory for shifts of energy spectra due to electron-phonon interaction (EPI), at 300 K, the 'pure electronic' contributions and the contributions from EPI to R-1 line, R-2 line, and U band of GGG:Cr3+ as well as their PS have been calculated, respectively. The total calculated results are in good agreement with all the experimental data. Their physical origins have been explained. It is found that the mixing-degree of \t(2)(2)(T-3(1))e(4)T(2)] and \t(2)(3 2)E] base-wavefunctions in the wavefunctions of R-1 level of GGG:Cr3+ is considerable under normal pressure, and the mixing-degree rapidly decreases with increasing pressure. The change of the mixing-degree with pressure plays a key role for PS of R-1 line or R-2 line. At 300 K, both the temperature-independent contribution to R-1 line (or R-2 line or U band) from EPI and the temperature-dependent one are important. The remarkable difference between pressure-dependent behaviors of PS of R-1 lines of GGG:Cr3+ and GSGG:Cr3+ results from the differences of their microscopic properties. The features of emission spectra of GGG:Cr3+ at various pressures have satisfactorily been explained. |
