Abstract
The time dependence of the photoluminescence signal is calculated for a the rmalized population of excitons in quantum well heterostructures. A thermal equilibrium between excitons and free carriers either in the well or in th e barrier is assumed. The result of our calculations is compared to experim ental data obtained on shallow quantum wells. We show that the decay of the ir excitonic photoluminescence has very little to do with the true exciton decay time.
