文摘

We hereby report hydrothermal syntheses of new microstructures of semiconducting ZnO. Single-crystalline prismaticZnO microboxes formed by nanowalls and hexagonal hollow microdisks closed by plates with micron-sized inorganicfullerene-like structures have been made in a base-free medium through a one-step hydrothermal synthesis withthe help of n-butanol (NB). Structures and morphologies of the products were confirmed by results from powderX-ray diffraction and scanning electron microscopy. NB has been found to play a crucial role in the growth of thesehollow structures. It is indicated that these hollow ZnO crystals were grown from redissolution of interiors. TheseZnO microboxes exhibit a band emission in the visible range, implying the possession of a high content of defects.
