Colloidal Route Preparation and Photoluminescent Properties of ZnO and ZnS/ZnO Nanoarrays on Zn Substrates

Single crystal state ZnO nanorod and nanosheet arrays, as well as double-layered ZnS/ZnO composite nanorod arrays, were prepared on Zn substrates via colloidal route. X-ray diffraction(XRD), scanning electron microscopy(SEM), high-resolution transmission electron microscopy(HRTEM), and X-ray photoelectron spectroscopy were used to characterize the composition, structure and morphology of the product. The effects of reaction temperature and time on the morphology of the product were discussed and the control of surfactant on the morphology of the products in liquid phase synthesis was investigated. The luminescent properties of the synthesized nanoarray material were studied via photoluminescence technology.
