Notes:
The light emitting properties of ZnS/ZnSe and ZnSTe/ZnSe strained II–VI superlattices are investigated. Room-temperature stimulated emission by photopumping in the deep-blue spectral region is observed. An upper limit of threshold carrier density required to achieve lasing is estimated to be 3×1018/cm3.The peak of stimulated emission is several tens of meV red shifted from the spontaneous emission peak, suggesting that exciton-exciton scattering is involved in the stimulated emission process. © 1995 American Institute of Physics.
