| Abstract: | CdSe/ZnS，CdTe/ZnS and CdSexTe1-x/ZnS core/shell luminescent composite nano-particles were synthesized in the aqueous to coat ZnS on water-soluble CdSe，CdTe and CdSexTe1-x QD (Quantum Dots) core.The properties of the as-prepared nano-particles were characterized by fluorescence spectra and transmission electron microscopy (TEM).Fluorescence spectra were used to probe the effect of time and the quantity of stable reagent (mercaptoethylic acid) on the spectral characterization of core/shell nano-particles. |
