摘要：

A kind of novel urchin-like hierarchical ZnO micro-/nano-structure film has been constructed on the Zn foil substrate by a simple one-step vacuum thermal evaporation process using a mixture of ZnS and graphite powder as a source. Individual ZnO micro-/nano-structures and bamboo-like branches have been characterized using field emission scanning electron microscope (FE-SEM) and high resolution transmission electron microscope (HRTEM). The results showed that different urchin-like ZnO structures probably originates from various microsphere precursors. Reasonable formation mechanism of the hierarchical ZnO micro- or nano-structures have been proposed on the base of the obtained information. The study also explored the properties of the ZnO micro-/nano-structure film performing wettability and Raman and room-temperature photoluminescence. The realization of the hierarchical structures can encourage potential opportunities for high technological applications.
