  • Publication number: 20180108457
    Abstract: A coated article includes an applied transparent electrically conductive oxide film of niobium doped titanium oxide. The article can be made by using a coating mixture having a niobium precursor and a titanium precursor. The coating mixture is directed toward a heated substrate to decompose the coating mixture and to deposit a transparent electrically conductive niobium doped titanium oxide film on the surface of the heated substrate. In another coating process, the mixed precursors are moved toward the substrate positioned in a plasma area between spaced electrodes to coat the surface of the substrate. Optionally, the substrate can be heated or maintained at room temperature. The deposited niobium doped titanium oxide film has a sheet resistance greater than 1.2 ohms/square and an index of refraction of 1.00 or greater. The chemical formula for the niobium doped titanium oxide is Nb:TiOx where X is in the range of 1.8-2.1.
