Abstract

Hierarchical ZnO nanostructures assembled from nanosheets are obtained through a facile hydrothermal route. The structure and morphology of the resultant products were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), and transmission electron microscope (TEM). The experimental results indicated that the as-synthesized ZnO nanosheets have an average thickness of approximately 50 nm. The possible mechanism for hierarchical ZnO nanostructures has been discussed in detail, and it was found that sulfur powder plays a critical role in the morphology of the products. Room temperature photoluminescence property of the hierarchical ZnO nanostructures shows an ultraviolet emission peak at 385 nm.
