Abstract
A detailed Raman microscopy and spectroscopy study of metal ions (La, Cr, Al, Fe and Sm) doping of ZnO as nanostructured thin films prepared by spray deposition method is presented. Raman spectroscopy performed under $\lambda=532 \ nm$ excitation at room-temperature is discussed. In particular, analysis of the frequencies, linewidths and width at half maximum (FWHM) of the Raman modes to show the influence of nature of metal dopants effects on the wurtzite crystalline structure of the ZnO nanostructured thin films.
