Fine structure of isolated Mn 2+ 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 Mn 2+ ions is observed when an applied magnetic field satisfies the Mn 2+ electron paramagnetic resonance (EPR) condition. This suggests that a spin‐dependent energy transfer from excitons to intra‐Mn excitations occurs at the EPR condition.
