- We report a facile aqueous phase synthesis for preparing water-soluble inverted core/shell ZnSe/CdSe semiconductor nanocrystals. The samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and their optical properties were investigated by using UV-vis-NIR spectrophotometer and fluorescence spectrophotometer. The results indicate that the synthesized ZnSe/CdSe nanocrystals are inverted core/shell structure with diameter of about 5 nm. Furthermore, their absorption band-edge is red-shifted with the growth of CdSe shell; correspondingly, their emission wavelength can be tuned from 460 nm to 604 nm.
