摘 要：By means of both the theory for pressure-induced shifts（PS）of energy spectra and the theory for shiftsof energy spectra due to electron-phonon interaction（EPI）,at 300K,the‘pure electronic’contributions and the contri-butions from EPI to R1line,R2line,and U band of GGG:Cr3+as well as their PS have been calculated,*** total calculated results are in good agreement with all the experimental *** physical origins have *** is found that the mixing-degree of|t（2～2）(3T1)e4T2〉and|t232E〉base-wavefunctions in the wavefunctions ofR1level of GGG:Cr3+is considerable under normal pressure,and the mixing-degree rapidly decreases with *** change of the mixing-degree with pressure plays a key role for PS of R1line or *** 300K,boththe temperature-independent contribution to R1line（or R2line or U band）from EPI and the temperature-dependentone are *** remarkable difference between pressure-dependent behaviors of PS of R1lines of GGG:Cr3+andGSGG:Cr3+results from the differences of their microscopic *** features of emission spectra of GGG:Cr3+at various pressures have satisfactorily been explained.
