摘要：

The ZnO properties strongly depends on its shape and structure, thus it is significant to control the growth of ZnO. In this report, the wurtize ZnO particles were synthesized via Zn(CH3COO)(2) hydrolyzing in methanol using chemical deposition method. The size and shape of ZnO particles were controlled well by adding H2O. Without adding H2O or with little volume ratio of adding H2O/methanol, the ZnO nanoparticle film was synthesized. On increasing volume ratio, the shape of ZnO particles varied from irregular particle, plate into regular cone with the size changing from nano-scale into micro-scale. Moreover, the height of the cone decreased as the volume of adding H2O increased. These clearly demonstrate that H2O could control the growth of ZnO particles. (c) 2005 Elsevier B.V.
