We report the results of a systematic investigation of the stimulated emission in \(\mathrm{ZnSSe} / \mathrm{ZnSe}\) superlattices, by time resolved luminescence and high excitation intensity magnetoluminescence. The stimulated emission is found to have excitation origin from localized states around

Photo-pumped lasing properties have been investigated in a CdSe/ZnSe/ZnSSE single quantum wells (SQWs) with the well-layer thickness (L W ) of 1, 2 and 3 monolayer (ML). At 20 K, the laser threshold for the SQW with L W = 1 ML was the lowest in spite of the smallest active layer thickness. The carri
