 powders were prepared by a simple co- precipitation method and analysed using X-ray diffraction (XRD) and Transmission Electron Microscopy (TEM). The XRD measurements revealed the formation of single phase Ni- doped ZnO up to Ni concentrations of x = 0.03. The Zn<sub>0.95</sub>Ni<sub>0.05</sub>O sample shows the formation of a secondary phase of NiO, which indicates the solubility limit of Ni in the ZnO matrix. The TEM micrograph shows the estimated grain size of doped & undoped ZnO to be approximately 20nm. Raman spectra of ZnO nanoparticles (ZnO-NPs), as well as the transition-metal-doped (5% Nickel) ZnO nanoparticles with the average size of 20 nm have been measured. A characteristic Raman peak at 434 cm<sup>-1</sup> is observed in the ZnO-NPs, whereas the doped Zn<sub>1-x</sub> Ni<sub>x</sub> O specimens (x= 1mol%, 3mol% and 5mol%) showed characteristic peaks shifted in wavenumber at 434, 430, and 425 cm-1, respectively. These peaks can be related to the formation of NiO species in the doped ZnO-NPs.&picture=http://www.aascit.org/aascit/decorators/img/journal/891.jpg)
