Abstract
We show that a lineshape analysis of the photoluminescence spectra of GaAs/AlGaAs quantum wells can provide valuable information on the processes ruling the exciton recombination. In particular the relevance of resonant Rayleigh scattering in the case of resonant excitation at various lattice temperatures and the validity of the thermalization hypothesis under different experimental conditions have been investigated.
