摘要：
We demonstrate experimentally that the exciton luminescence rise times in GaAs/AlxGa1-xAs quantum wells oscillate as a function of laser excess energy. We interpret these results as the occurrence of a selective optical-phonon assisted exciton formation. Experiments on doped quantum wells confirm our exciton formation model.
