    Compositional studies of various metal oxide coatings on glass
    (Thin Solid Films, 9019-02) Ajayi, E.O.B; Akanni, M.S; Lambi, John Ngolui; Jeynes, Chris
    Oxide films were deposited on soda-lime glass substrates by pyrolysis of indium, copper, chromium and aluminium acetylacetonates. Ion beam analysis and X-ray photoelectron spectroscopy were performed showing that the appropriate metal oxides were deposited. The indium and chromium oxide films appeared to be quite clean but the copper and aluminium oxide films were porous and had very high concentrations of carbon with associated oxygen. The copper film also had significant free copper near the surface. Significant leaching of sodium and potassium from the substrate in these two latter films was also observed. Promising optical absorbance was observed for the chromium film
