Abstract: Anti-sparkle substrates include a plurality of features extending from a first major surface of the anti-sparkle substrate. In aspects, a feature of the plurality of features includes a feature concentration of one or more of silver, rubidium, or cesium that is non-zero at the first major surface and is greater than a corresponding concentration of a region of the first major surface excluding the plurality of features. In aspects, a feature of the plurality of features includes a gradient refractive index profile. A feature refractive index of the feature at the first major surface is greater than a substrate refractive index by about 0.03 or more. Methods include exposing a plurality of portions of a first major surface of a substrate to a source of one or more of silver ions, rubidium ions, or cesium ions to form a plurality of features in that include the plurality of portions.

Abstract: An optical metasurface includes a substrate and a plurality of nanostructures extending from a surface of the substrate and constructed of a material having an index of refraction. The plurality of nanostmctures are arranged in a plurality of unit cells comprising a dimension that is less than or equal to twice an effective wavelength of light incident on the optical metasurface, divided by the sinusoid of a deflection angle that the optical metasurface is designed to deflect the light. The plurality of nanostructures are asymmetrically arranged along a deflection direction. A unit cell aspect ratio of the plurality of nanostmctures is greater than or equal to 3, and a product of the unit cell aspect ratio and the index of refraction of the material is greater than or equal to 8.

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.

Abstract: A textured article is described herein comprising a substrate comprising a textured region defined on a primary surface of the substrate, in which the textured region comprises (a) a Vmp/Sq of at least 0.084, (b) a Vmp/Sq of at least 0.084 and an Smrk2 of at least 90%, and/or (c) a Vmp of at least 10 nm and an Sdq of 0-0.1. The textured article generally has good abrasion resistance and optical properties including antiglare, haze, sparkle, and distinctness of image. A method for making a textured article is also described herein comprising removing a first portion of a primary surface of a substrate through holes penetrating through a stop layer to the primary surface to form seed depressions and unremoved portions, removing the stop layer, and then removing a second portion of the primary surface comprising the seed depressions and the unremoved portions.

Abstract: A glass article comprises a film layer deposited on a glass substrate. The film layer has a melting point less than 450° C. and comprises a thickness and a primary surface. The primary surface defines at least one elevated surface protruding relative to the at least one relief surface. The elevated surface forms a periodic pattern defined by an etch mask, and the relief surface is defined as an inverse pattern of the etch mask. The duration of an etching process applied to the film layer defines a ratio of a first area of the elevated surface to a second area of the relief surface.
