Abstract

F-co-doped Palladium Tin Oxide (PTO) thin films were pyrolytically deposited on glass substrate at 450<SUP>0</SUP>C using an alcoholic precursor solution consisting of Tin (IV) Chloride (SnCl<SUB>4</SUB>.5H<SUB>2</SUB>O), Palladium Chloride (PdCl<SUB>2</SUB>) and Ammonium Fluoride (NH<SUB>4</SUB>F). A resistivity of 0.3-6.9×10<SUP>-2</SUP>Ωcm was obtained in F-co-doped PTO films prepared with a Pd content of 3.68at% and F content of 0 – 23.96at% under optimized conditions. The optical properties were studied in the UV/VIS/NIR region. The optical bandgap of the films laid in the range 3.945 – 4.014 eV. Using dispersion analysis with Drude and Kim terms, optical constants were determined from spectro-photometric measurements for films on glass.
