Radial and quasi-aligned ZnO nanorod arrays were prepared on Si(111) substrates by a simple vapor phase method using Zn and zinc acetate dihydrate (ZA) as the source materials. X-ray diffraction, field emission scanning electron microscopy, Raman scattering and photoluminescence were used to characterize the structural and optical properties of the obtained nanostructures. The growth mechanisms of the two kinds of ZnO nanostructures were discussed based on the growth conditions. The different decomposing rate of the ZA plays an important role in the initial nucleatio n of ZnO nanorods. (c) 2006 Elsevier B.V. All rights reserved.
