The effect of Sb-doping concentration on the optical behavior of SnO2 film deposited on glass substrates are analyzed and discussed. Optical measurements showed that the average optical transmittance decreased with increased Sb concentration, and each of absorbance, absorption coefficient and extinction factor were increased in same way and regularly with increasing the concentration of Sb. However the optical reflectance and the refractive index were irregularly increased in same way with increasing the concentration of Sb. A little decrease of energy gap from 3.96 to 4.015 eV with increasing Sb concentration is observed.
