Abstract
Time-resolved photoluminescence of ZnSe-ZnTe superlattices with differ ent Te concentrations has been measured in the picosecond time region. The samples show typical S1 (blue band) and S2 (green band) emissions in the time-integrated spectra. In the time-resolved spectra, both sa mples exhibit an asymmetrically broadened shallow component at the hig h-energy side of the luminescence band, indicating the presence of sha llow localized excitons due to long-range potential fluctuations.
