Time‐resolved photoluminescence of ZnSe–ZnTe superlattices with different 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 samples exhibit an asymmetrically broadened shallow component at the high‐energy side of the luminescence band, indicating the presence of shallow localized excitons due to long‐range potential fluctuations.
