A group of well-defined exciton transitions from the localized states were observed in ZnSe-Zn0.75Cd0.25Se double-superlattice structure. The photoluminescence and photoreflectance have been employed to study the subband transitions at low temperatures. At 1.4 K, except the two ground states and two higher subbands of n=1 light-hole and n=2 heavy-hole excitonic transitions, other four peaks (A, B, C, and D) also were observed in wider-well superlattice, Those peaks were attributed to the excitonic transitions from n=2 heavy-hole subband due to the fluctuation of well-barrier interface. Another localized excitonic transition from narrower-well superlattice appeared as increasing the modulated intensity in photoreflectance spectra. (C) 1998 American Institute of Physics.
