Abstract

Undoped and Fluorine-doped indium oxide (In2O3:F) thin films have been prepared by spray pyrolysis technique on heated glass substrates at 450°C from the Indium chloride (InCl3) and ammonium fluoride (NH4F). The effect of fluorine doping agent on the nonlinear optical properties was investigated using X-ray diffraction, electrical resistivity, transmission, and third harmonic generation (THG). The best value of nonlinear optical susceptibility χ(3) was obtained from the doped films with low electrical resistivity of 6 x 10-3 Ω cm. A strong third order nonlinear optical susceptibility χ(3) = 1.98 x10-11 (esu) of the studied films was found for the 5% doped sample..
