Growth of Thin Sheet Assembled Hierarchical ZnO Nanostructures

[摘要] 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 wasfound 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.
