The exciton dynamics in Zn 1-x Cd x Se/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 τ PL ) and thermal escape of carriers from the quantum well at relat
