The Optical Properties of Sb Doped SnO2 Thin Film Produced by Spin Coating

Abstract

In this study, there is investigated that the optical properties of the 0%, 1%, 2%, and 3% Sb doped SnO2 thin films produced by spin coating technique. The photon absorption of 3% Sb doped SnO2 thin film is very high while the non-doped and 2% Sb doped SnO2 thin films have low absorption and are close to each other. The extinction coefficient of thin films was calculated and its graph was plotted depend wavelength. Refraction indices and dielectric coefficients were calculated and the results interpreted using Herve&Vandamme, Moss and Ravindra relations. The Skin Depth and the optical conductivity characterizes depend band gap of all thin films are drawn and explained.
