Abstract: In this work a mixing SnO2and In2O3 precursors solutions were prepared by sol-gel method. About this mixture, thin films were elaborated by dip coating and were followed by annealing in air. Nanorods were obtained and were appeared for 20 % SnO2+ 80 % In2O3 of mixture. The morphology composition and structure layers were studies by scanning electron microscopy and X ray diffraction. The optical transmission of these films is in the order of (up to 95 %), with a band gap of 3.27eV. The best film showed a significant decrease of its square resistance R (down to12 /). This result is an excellent value obtained by sol-gel method.
