Structural and Optical Parameters of SnO2 Nanoparticle Deposited by Spray Pyrolysis

Abstract

SnO2 nanoparticle thin films are obtained using simple spray pyrolysis chemical process with 0.1 molar concentrations on glass substrate at: T = 300, 325 and 350 °C respectively. The deposited films were investigated using the appropriate method of characterization. The X-ray diffraction revolved that the deposited SnO2 nanoparticle thin films have tetragonal rutile structure. The scanning microscopy (SEM) and Atomic force microscopy (AFM) indicate that films are homogenous and uniform in all direction with small grain size (10–14) nm. The UV-visible spectrophotometry showed that the transmittance of the films is above 85% in the visible and band gap Eg around 4 eV.
