We study the time-resolved photoluminescence emission of InAs self-assembled quantum dots (QDs) incorporated in a GaAs/(AlGa)As quantum well. We show that the quantum well confinement affects the decay time of the dot photoluminescence. In addition, we use the strong dependence of the decay time on excitation energy and temperature to shed light on carrier relaxation mechanisms in QDs.
