COATED ARTICLE HAVING LOW-E COATING WITH IR REFLECTING LAYER(S) AND DOPED TITANIUM OXIDE BI-LAYER FILM DIELECTRIC AND METHOD OF MAKING SAME

摘要

A coated article includes a low emissivity (low-E) coating having at least one infrared (IR) reflecting layer of a material such as silver, gold, or the like, and at least one high refractive index bi-layer film of or including doped titanium oxide (e.g., TiO₂ doped with at least one additional element). The titanium oxide based bi-layer film may be of or include a first titanium oxide based layer doped with a first element, and an adjacent second titanium oxide based layer doped with a different second element.
