Formation and Raman scattering of seed‐like ZnO nanostructure

Abstract

Abstract This work demonstrates seed‐like ZnO nanostructure aggregated with nano‐entities using the colloid chemical method. The formation mechanism and optical properties of the ZnO nanostructure are studied. The X‐ray diffraction spectrum indicates that the ZnO nanostructures are polycrystalline pure wurtzite phase. Multiphonon processes in the nanostructure are identified from the Raman scattering spectra in the spectral range of 300–2000 cm −1 . A strong violet photoluminescence band emission was visible in the room temperature photoluminescence spectra. This work determines the quality of such crystals and extends the optical applications of ZnO nanostructures. Copyright © 2009 John Wiley & Sons, Ltd.
