Effect of strontium doping on characteristics of spray deposited SnO 2 thin films

Abstract

Growth and characterization of spray deposited strontium doped tin oxide thin films is presented. Strontium doped tin oxide films are polycrystalline with tetragonal structure. The films are uniform, crack-free and have relatively smooth surface. Spectroscopic ellipsometry analysis shows red shift in the optical band gap and decrease in refractive index upto 1% strontium doping.
