Abstract
AbstractThe effect of excitation level on the luminescence of ZnMnTe/ZnMgTe quantum‐well (QW) structures has been studied. We find that result depend strongly on the QW width and manganese concentration. The increasing optical pumping implies a degradation of the Mn2+ intracenter luminescence (IL) due to the interaction of the strongly excited Mn2+ system with the high density of excitons. The spectral and kinetic properties of the IL reveal the contribution of the Mn2+ ions located on the interface and inside the QW as well as the Mn2+ IL decay dependence on the QW width.
