Photoluminescence spectra of CdTe/CdMnTe quantum well structures in an external magnetic field

Abstract

The investigation of the photoluminescence spectra of CdTe/CdMnTe quantum well structures proves that the exciton localisation efficiency is governed by temperature, external magnetic field, and excitation energy. The polarization of the luminescence in a magnetic field suggests that the impurity related luminescence band is due to the recombination of electron states situated near the interface.
