摘要：

Photoluminescence spectra of Mn2+ in CdMnTe are investigated using tunable laser in a temperature range from 15 K to 80 K. The shift of the photoluminescence peak energy with the excitation energy is observed. From analysis using the shift and the photoluminescence width, we obtain the temperature dependencies of homogeneous and inhomogeneous broadening widths of the d-d transition. In addition, the effects of high hydrostatic pressure on the electron-phonon coupling strength and the homogeneous and inhomogeneous widths are investigated.
