Photoluminescence spectroscopy with high spatial resolution has been applied to study single CdSe quantum dots embedded in a semimagnetic ZnMnSe matrix. The exchange interaction between the exciton and Mn 2+ ions of the crystal matrix results in the formation of a ferromagnetically aligned spin comp
The photodegradation of CdSe quantum dots (QDs) is investigated by micro-photoluminescence (PL) measurements. With increasing exposure time of laser, the PL intensity of the QDs gradually decreases up to %25 s and remains constant after % 25 s. In contrast, the PL intensity of ZnCdSe quantum well (Q
