Effect of Sb-doping on Optical Properties of Fe2O3 Thin Films

Abstract

Fe2O3 and Sb doped Fe2O3 thin films with deferent percentage were
intended via spray pyrolysis technique. Effect of Sb doped on optical
parameters was studied utilizing Double beam spectrophotometer in order
to locate transmittance spectra. Absorbance was raised with accretion of Sb
concentration, same behavior was noticed for extinction coefficient. Energy
gap was decreased from 3.25 eV for undoped film to 3.0 eV on 3% Sbdoping., while Reflectance, absorption coefficient and refractive index
were shown the opposite behavior by decrease their values with increasing
of Sb.
