Abstract

A novel method for the synthesis of water-soluble CdSe and CdSe/CdS quantum dots (QDs) under the assistance of high-intensity ultrasonic irradiation is reported. As-prepared CdSe/CdS QDs were characterized by X-ray powder diffraction and high-resolution transmission electronmicroscopy. The absorption and fluorescence emission spectra were measured to investigate the effect of CdS passivation on the electronic structure of the quantum dots. After the growth of CdS shell, the photoluminescence quantum yields of CdSe/CdS core-shell quantum dots increased three times more than that of the original CdSe QDs. The QDs were successfully used for the fluorescence imaging of cells and blood capillary.
