Abstract
Luminescence spectra in GaAs/Gal−XAlX As quantum wells in magnetic fields show the recombination from several Landau levels, filled with optically excited electrons and holes. A comparison of this luminescence with low power absorption spectra (involving empty states) shows in detail the changes of the optical properties with electron and hole density. For densities > 1012cm−2, a decrease of the bandgap of twice the exciton binding energy, and which is independent on density is observed. Furthermore an excitonic behaviour of the ground state and a 20% enhancement of the effective mass is observed.
