✦ Synopsis

Photoluminescence (PL) spectra, time profiles of PL intensity and PL excitation spectra (PLE) for inter 3d multiplets (3d-MS) transition of Mn 2 are observed in the semimagnetic semiconductor CdMnTe under high pressures. Those of inter 3d-MS and inter quantum levels (QL) transitions are also observed in quantum wells (CdTe/Cd 0.4 Mn 0.6 Te). The decay processes in these excited states are discussed. The decay process to the excited states of infrared photoluminescence is also discussed for various concentrations. In these excited states it is considered that large lattice relaxation is essential.
