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
We have investigated the properties of neutral and charged excitons in single CdSe/ZnSe QD photodiodes by m-photoluminescence spectroscopy. By applying a bias voltage, we have been able to control the number of electrons in a single QD by shifting the energy levels of the QD with respect to the Ferm
