Abstract: Embodiments of articles including a low-contrast anti-reflection coating are disclosed. The coated surface of such articles exhibits a reduced difference in reflectance between a pristine state and when a surface defect is present. In one or more embodiments, the coated surface of such articles exhbits a first average reflectance in the range from about 0.6% to about 6.0% in a pristine condition and a second avearge reflectance of about 8% or less after removal of a surface thickness of the anti-reflection coating. In other embodiments, the coated substrate exhibits a second average reflectance of about 10% or less, when the coated surface comprises a contaminant. In some embodiments, the coated substrate exhibits a first color coordinate (a*1, b*1) in a pristine condition and a second color coordinate (a*2, b*2) after the presence of a surface defect such that Aa*b* is about 6 or less.

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.
