Is luminescence from quantum wells due to excitons?
Femtosecond luminescence measurements combined with pump-probe experiments using selective excitation of either free carriers or excitons have been performed. The time-resolved luminescence spectra show a striking disparity compared with recently published theoretical models. Large differences in the pump-probe spectra are observed for resonant and non-resonant (continuum) pumping. The origin of these differences is discussed.
