Effect of fluorine incorporation on the third-order nonlinear-optical properties of indium oxide thin films prepared by spray pyrolysis
Résumé
Undoped and Fluorine-doped iridium oxide (In(2)O(3):F) thin films have been prepared by spray pyrolysis technique on heated glass substrates at 450 degrees C from the Indium chloride (InCl(3)) and ammonium fluoride (NH(4)F). 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 chi((3)) was obtained from the doped films with low electrical resistivity of 6 x 10(-3) Omega cm. A strong third order nonlinear optical susceptibility chi((3)) = 1.98 x10(-11) (esu) of the studied films was found for the 5% doped sample.
