Abstract: One or more aspects of the disclosure pertain to an article including an optical film structure disposed on an inorganic oxide substrate, which may include a strengthened or non-strengthened substrate that may be amorphous or crystalline, such that the article exhibits scratch resistance and retains the same or improved optical properties as the inorganic oxide substrate, without the optical film structure disposed thereon. In one or more embodiments, the article exhibits an average transmittance of 85% or more, over the visible spectrum (e.g., 380 nm-780 nm). Embodiments of the optical film structure include aluminum-containing oxides, aluminum-containing oxy-nitrides, aluminum-containing nitrides (e.g., AlN) and combinations thereof. The optical film structures disclosed herein also include a transparent dielectric including oxides such as silicon oxide, germanium oxide, aluminum oxide and a combination thereof. Methods of forming such articles are also provided.
