Abstract: An optical film structure that includes: an optical film comprising a physical thickness from about 50 nm to about 3000 nm, and a silicon-containing nitride or a silicon-containing oxynitride. The optical film exhibits a maximum hardness of greater than 18 GPa, as measured by a Berkovich Indenter Hardness Test over an indentation depth range from about 100 nm to about 500 nm on a hardness stack comprising a test optical film with a physical thickness of about 2 microns disposed on an inorganic oxide test substrate, the test optical film having the same composition as the optical film. Further, the optical film exhibits an optical extinction coefficient (k) of less than 1×10−2 at a wavelength of 400 nm and a refractive index (n) of greater than 1.8 at a wavelength of 550 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 retains its 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 prevented by inserting a crack mitigating layer between the glass substrate and the film.

Abstract: 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.

Abstract: According to one or more embodiments described herein, a coated article may comprise a transparent substrate and an optical coating. The transparent substrate may have a major surface, and the optical coating may be disposed on the major surface of the transparent substrate and form an air-side surface. The optical coating may comprise one or more layers of deposited material and one or more light-altering features which may reduce oscillations in the reflectance spectrum of the coated article. The coated article may exhibit a maximum hardness of about 8 GPa or greater, have an average photopic transmittance of about 50% or greater, and exhibit an angular color shift of less than about 10 from a reference illumination angle in a range of 0-10 degrees to an incident illumination angle in a range of 30-60 degrees relative to the air-side surface.

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 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.

Abstract: A method of manufacturing a laminated glass article is disclosed that includes forming a laminated glass article with at least one glass cladding layer and a glass core layer adhered to the glass cladding layer. The glass core layer is amenable to crystallization and optionally has a viscosity amenable to forming by a fusion lamination method. The method further includes removing a portion of the laminated glass article such that the glass core layer is exposed on at least one edge of the laminated glass article, and crystallizing at least a portion of the exposed glass core layer. A crystallized or semi-crystallized surface of the exposed glass core layer has a lower CTE than a remainder of the glass core layer. A laminated glass article and a glass article having a crystalline or semi-crystalline surface portion that is integral with a bulk of the glass body are also disclosed.

Abstract: A glass article having a low level of grainy appearance that can appear to have a shift in the pattern of the grains with changing viewing angle of a display, or “sparkle.” The glass article—which, in some embodiments, is a transparent glass sheet—has small-angle-scattering properties and/or distinctness-of-reflected-image (DOI), leading to improved viewability in display applications, especially under high ambient lighting conditions. In some embodiments, the antiglare surface of the glass sheet is an etched surface, with no foreign coating present on the antiglare surface.
