    • Abstract

       

      ZnO nanoflowers were prepared by the hydrothermal method and studied by X-ray diffraction, Raman spectroscopy, scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy and photoluminescence. ZnO nanoflowers with star-like morphology were of pure wurtzite phase. The edges of the petals were composed of assemblies of smaller nanocrystallites. Green and orange emissions in photoluminescence were attributed to O vacancies and O interstitials, respectively. Furthermore, ZnO nanoflowers demonstrated the effective photocatalytic activities, and O vacancies and O interstitials were considered to be the active sites of the ZnO photocatalyst.
