Abstract

ITO nanoparticles were obtained by combustion reaction of urea as fuel. The gel form structures were fired at 350°C in furnace for 20 min to yield powdery products and these products were calcined to five different temperatures from 100°C to 500°C for an hour to yield ITO powders. From the scanning electron microscopy (SEM) photographs and particle size analysis the average sizes of the cubic particle of powders are found to be less than 15 nm and less than 20 nm respectively. The ratio of doping concentration In/Sn is 90/10 and 80/20. The X-ray diffraction (XRD) data were evaluated by Scherer equation for the estimation of the average crystal size of the powders (less than 20 nm) for 90/10 and (less than 25 nm) for 80/20. The synthesized ITO powder characterized by XRD, UV-Vis-NIR and PL shows high specific surface area and possesses small primary crystallite size and good optical band gap.
