摘要： An ultraviolet light-resistant article that includes: a substrate having a glass or glass-ceramic composition and first and second primary surfaces; an ultraviolet light-absorbing element having a an absorptivity greater than 50% at wavelengths from about 100 nm to about 380 nm and a thickness between about 10 nm and about 100 nm; and a dielectric stack formed with a plasma-enhanced process. Further, the light-absorbing element is between the substrate and the dielectric stack. Alternatively, the light-absorbing element can include one or more ultraviolet light-resistant layers disposed within the dielectric stack over the first primary surface.

摘要： A coated article is described herein 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.

摘要： 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.

摘要： 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 an optical interference layer. The optical interference layer may include one or more sub-layers that exhibit different refractive indices. In one example, the optical interference layer includes a first low refractive index sub-layer and a second a second high refractive index sub-layer. In some instances, the optical interference layer may include a third sub-layer.

摘要： Durable and scratch resistant articles including low-reflectance optical coating with gradient portion. In some embodiments, an article comprises: a substrate comprising a first major surface; and an optical coating disposed over the first major surface. The optical coating comprises: a second major surface; 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 0.05 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 a single side photopic average light reflectance of 3% or less, and a maximum hardness from 10 GPa to 30 GPa.

摘要： Optically transparent articles and structures that include or are otherwise disposed on a substantially transparent substrate. These articles and structures also include a stack of N (N>2) bi-layers on the substrate, the stack having a thickness of at least 5 nm. Each bi-layer is defined by (a) a first layer; and (b) a second layer disposed on the first layer, the layers having at least one of different compositions and different microstructures. The stack has a stack refractive index between about 1.2 and about 2.2 or between about 100% and about 150% of a refractive index of the substrate, and a stack hardness of 15 GPa or greater when measured with a Berkovich Indenter Hardness Test along an indentation depth in the range from about 10% to about 50% of the thickness of the stack disposed on a glass test substrate having a hardness between 6.5 and 8 GPa.
