Abstract

Magnetic-ion-containing self-assembled quantum dots based on II-VI semiconductors are investigated by time-resolved optical spectroscopy. It is found that the dynamical properties of excitons confined in quantum dots depend on the relative position of intra-Mn transition with respect to the quantum-dot-related emission. When the intra-Mn transition energy is smaller than the dot emission energy, then the decay time of excitons in quantum dots increases with increasing magnetic field. When the intra-Mn transition energy is larger, no influence of the magnetic field on the recombination dynamics of excitons is found. The first case corresponds to CdMnSe/ZnSe structures, while the second one is observed in CdMnTe/ZnTe magnetic quantum dots.
