Large Scale Synthesis of Dendritic CdS Nanostrucutres

Abstract:

Single crystalline CdS dendrites were successfully synthesized in high yield by a simple and facile hydrothermal method. The allyl thiourea and CdCl2•5H2O were used as raw materials for the synthesis of dendritic CdS nanostructures for the first time. The as-prepared products were characterized by X-ray powder diffraction, scanning electron microscopy, transmission electron microscope and selected area electron diffraction. The results demonstrate that the petal in an individual dendritic CdS nanoarchitecture is single crystalline and prefers growth along the [101] direction. The reaction parameters affected the CdS morphology were investigated systematically. It is found that the morphology of the samples are strongly dependent on the cadmium source, sulfide source, the reaction time and the solvent, the temperature has no effect on the morphology of the products. The possible mechanism was proposed for the formation of dendritic CdS nanostructures
