Includes bibliographical references.
Colloidal semiconductor nanocrystals or quantum dots have attracted much attention recently with their unique optical properties. Here we present a novel approach to synthesize ZnTe/ZnSe core/shell tunable quantum dots. Characterizations such as transmission electron microscopy, wavelength dispersive X-ray spectroscopy, powder x-ray diffraction are employed to give evidence for the core/shell structure. Absorption, and photoluminescence spectra demonstrate the tunability of this ZnTe/ZnSe core/shell system, and fluorescence lifetime decays suggest a core/shell structure is made.
