Fabrication of ZnO nanorods by simplified spray pyrolysis

Abstract

ZnO layers were deposited by a simple and cost-effective spray pyrolysis using zinc chloride aqueous solutions on glass substrates at 600 °C. The structural properties of nanorods were characterized by Xray diffraction (XRD), scanning electron microscopy (SEM). XRD studies showed that the films were at polycrystalline form and oriented along (002) direction preferentially and other observed orientations were (102), (103) and (004). The standard and the calculated lattice constants are in consistence. It was also observed that the deposited films were ZnO with hexagonal structure andsurfaces of the films are found to be nonhomogeneous with hexagonal shaped rods.
