Facile hydrothermal synthesis of novel ZnO nanocubes

In this paper, we reported the synthesis of cubic ZnO nanostructures by a facile hydrothermal route at mild reaction temperature without the addition of any surfactant. The as-obtained ZnO nanocubes are well crystalline and with an average size of 200 nm. The dependence of morphologies on growth parameters was systematically investigated. Cathodoluminescence of as-grown ZnO nanocubes shows a strong ultraviolet emission and a poor blue emission peak at room temperature. (C) 2010 Elsevier B.V. All rights reserved.
