Abstract: We have investigated the optical properties of GaMnAs/AlAs quantum wells (QWs) grown by molecular beam epitaxy under relatively high substrate temperatures (400 and 450 degrees C) and low Mn concentrations (<= 0.1%). We have studied the time- and polarized-resolved photoluminescence emission as a function of the laser power and an applied magnetic field. Several anomalous results have been observed including long decay times, enhancement of the diamagnetic shift and reduction in the polarization degree with increasing Mn concentration.
