The article exhibits a hardness of 8 GPa or greater measured at an indentation depth of about 100 nm or a maximum hardness of 9 GPa or greater measured over an indentation depth range from about 100 nm to about 500 nm, the hardness and the maximum hardness measured by a Berkovich Indenter Hardness Test. Further, the article exhibits a single-side photopic average reflectance that is less than 1%.

Abstract: An article that includes: a glass, glass-ceramic or ceramic substrate comprising a primary surface; at least one of an optical film and a scratch-resistant film disposed over the primary surface; and an easy-to-clean (ETC) coating comprising a fluorinated material that is disposed over an outer surface of the at least one of an optical film and a scratch-resistant film. The at least one of an optical film and a scratch-resistant film comprises an average hardness of 12 GPa or more. Further, the outer surface of the at least one of an optical film and a scratch-resistant film comprises a surface roughness (Rq) of less than 1.0 nm. Further, the at least one of an optical film and a scratch-resistant film comprises a total thickness of about 500 nm or more.

Abstract: Embodiments of this disclosure pertain to articles that exhibit scratch-resistance and improved optical properties. In some examples, the article exhibits a color shift of about 2 or less, when viewed at an incident illumination angle in the range from about 0 degrees to about 60 degrees from normal under an illuminant. In one or more embodiments, the articles include a substrate, and an optical film disposed on the substrate. The optical film includes a scratch-resistant layer and a refractive index gradient. In one or more embodiments, the refractive index includes a refractive index that increases from a first surface at the interface between the substrate and the optical film to a second surface. The refractive index gradient may be formed from a compositional gradient and/or a porosity gradient.

Abstract: One or more aspects of the disclosure pertain to an article including an optical film structure disposed on a 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 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.
