Abstract
The optical property of a Zn0.8Cd0.2Se-ZnSe strained-layer superlattic e (SLS) has been investigated by making use of photoluminescence and t ime-resolved spectra. It is found that the donor-acceptor pair (DAP) b and shifts towards lower energy with decreasing excitation density and increasing delay time. The luminescence lifetime of the DAP band is s lower than that of the exciton luminescence. On the basis of these res ults the DAP band originates from the radiative recombination of the d onor-acceptor pair in Zn0.8Cd0.2Se-ZnSe SLS. (C) 1997 Elsevier Science S.A.
