Abstract
The exciton dynamics in Zn1-xCdxSe/ZnSe multiple quantum wells have been investigated by temperature-dependent time-resolved photoluminescence experiments. A polariton effect (leading to a linear T-dependence of the decay time tau(PL)) and thermal escape of carriers from the quantum well at relatively high temperature (resulting in a decrease of tau(PL) With the temperature) are observed in samples of different stoichiometry and well.
