Abstract: An article that includes: an inorganic oxide substrate having opposing major surfaces; and an optical film structure disposed on a first major surface of the substrate, the optical film structure comprising one or more of a silicon-containing oxide, a silicon-containing nitride and a silicon-containing oxynitride and a physical thickness from about 50 nm to less than 500 nm. 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: Durable and scratch resistant articles including an optical coating with a gradient. An article comprises: a substrate; and an optical coating having a thickness and a first gradient portion. A refractive index of the optical coating varies along a thickness of the optical coating. The difference between the maximum refractive index of the first gradient portion and the minimum refractive index of the first gradient portion is 0.1 or greater. The absolute value of the slope of the refractive index of the first gradient portion is 0.1/nm or less everywhere along the thickness of the first gradient portion. The article exhibits an average single-surface reflectance of 15% to 98% over the wavelength range 400 nm-700 nm. The article also exhibits a maximum hardness in the range from about 10 GPa to about 30 GPa.

Abstract: A coated article with a substrate having a major surface that comprises a first portion and a second portion that is curved or faceted; and an optical coating on the major surface that forms an anti-reflective surface. A first direction is normal to the first portion and is not equal to a plurality of second directions that are normal to the second portion, and the angle between the first direction and each of the second directions is from about 10 degrees to 60 degrees. Further, the coated article exhibits at the first and second portion a hardness of about 8 GPa or greater at an indentation depth of about 100 nm or greater. Further, the coated article exhibits a single side maximum reflectance of about 3% or less as the first and second portion, wherein the reflectance is measured in a range from about 425 nm to about 950 nm.

Abstract: One or more aspects of the disclosure pertain to an article including a film disposed on a glass substrate, which may be strengthened, where the interface between the film and the glass substrate is modified, such that the article has an improved average flexural strength, and the film retains key functional properties for its application. Some key functional properties of the film include optical, electrical and/or mechanical properties. The bridging of a crack from one of the film or the glass substrate into the other of the film or the glass substrate can be suppressed by inserting a nanoporous crack mitigating layer between the glass substrate and the film.

Abstract: Embodiments of durable, anti-reflective articles are described. In one or more embodiments, the article includes a substrate and an anti-reflective coating disposed on the major surface. The article exhibits an average light transmittance of about 94% or greater over an optical wavelength regime and/or an average light reflectance of about 2% or less over the optical wavelength regime, as measured from an anti-reflective surface. In some embodiments, the article exhibits a maximum hardness of about 8 GPa or greater as measured by a Berkovich Indenter Hardness Test along an indentation depth of about 50 nm or greater and a b* value, in reflectance, in the range from about −5 to about 1 as measured on the anti-reflective surface only at all incidence illumination angles in the range from about 0 degrees to about 60 degrees under an International Commission on Illumination illuminant.

Abstract: A display article is described herein that includes: a substrate comprising a thickness and a primary surface; a textured surface region; and an antireflective coating disposed on the textured surface region. The textured surface region comprises structural features and an average texture height (Rtext) from 50 nm to 300 nm. The substrate exhibits a sparkle of less than 5%, as measured by PPD140, and a transmittance haze of less than 40%, at a 0° incident angle. The antireflective coating comprises alternating high refractive index and low refractive index layers. Each of the low index layers comprises a refractive index of less than or equal to 1.8, and each of the high index layers comprises a refractive index of greater than 1.8. The article also exhibits a first-surface average photopic specular reflectance (% R) of less than 0.3% at any incident angle from about 5° to 20° from normal at visible wavelengths.
