Sol-gel derived 6SrO·6BaO·7Al2O3 thin films using metal alkoxides

A novel 6SrO·6BaO·7Al2O3 (S6B6A7) thin film has been deposited onto soda lime float glass via sol-gel dip coating technique. The optical and electrical properties of S6B6A7 films annealed in air and H2 atmosphere have been investigated. The structural and compositional properties of the S6B6A7 thin films have been investigated using Fourier transferred infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS). The S6B6A7 films prepared using 5 (wt.%) sol and annealed at 450 °C in air and H2 atmosphere exhibit an average transmittance of over ∼91% in wide visible range. The electrical properties of the S6B6A7 films affect film thickness as revealed by sheet resistance measurements. The sheet resistance of the 150 nm S6B6A7 films was 67.85 and 6.06 kilo ohms per square for air and H2 annealed, respectively.
