摘要:
A coated article includes a pyrolytic 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 one embodiment of the invention, the method is practiced using a vaporized coating mixture including a vaporized niobium precursor; a vaporized titanium precursor, and a carrier gas to deposit a niobium doped titanium oxide film having a sheet resistance greater than 1.2 and an index of refraction of 2.3 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.
