Abstract

Fine structure of isolated Mn²⁺ ions in CdMnSe/ZnSe quantum wells (QWs) is revealed by optically detected magnetic resonance (ODMR) recorded by monitoring both exciton emission and intra-Mn luminescence in the presence of simultaneous microwave irradiation. A large decrease of photoluminescence (PL) intensity of excitons and an increase of PL intensity of Mn²⁺ ions is observed when an applied magnetic field satisfies the Mn²⁺ electron paramagnetic resonance (EPR) condition. This suggests that a spin-dependent energy transfer from excitons to intra-Mn excitations occurs at the EPR condition.
