A highly efficient solvothermal route towards starfish-shaped CdS nanostructures and CdSe nanowires

Starfish-shaped CdS nanostructures and CdSe nanowires were synthesized through highly efficient solvothermal route. The prepared nanostructures were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and ultraviolet-visible spectroscopy (UV-Vis). The effect of pH on the morphology of nanostructures and the growth mechanism of CdSe nanowires was investigated. It can be concluded that pure CdS and CdSe nanostructures with high monodispersity can be successfully synthesized, and the pH has great effect on the formation of CdS nanostructure. Meanwhile, layered structures were considered a kind of intermediate in the growth of CdSe nanowires.
