A glass article is provided (and methods of making the same) that includes: a glass substrate comprising a thickness and a first primary surface; and a porosity-graded layer that extends from the first primary surface of the substrate to a first depth within the substrate. The first depth is from about 250 nm to about 3000 nm. The porosity-graded layer comprises a plurality of pores having an average pore size from about 5 nm to 100 nm. The article comprises a single-side average reflectance of less than 9% at an incident angle of 60 degrees across a spectrum from 350 nm to 2000 nm. Further, the porosity-graded layer comprises a surface porosity at the first primary surface and a bulk porosity at the first depth, the surface porosity greater than the bulk porosity.

A preparation method for a high-refractive index hydrogenated silicon film, a high-refractive index hydrogenated silicon film, a light filtering lamination and a light filtering piece. The method includes: (a) by magnetic controlled Si target sputtering, Si deposits on a base body, forming a silicon film, which (b) forms an oxygenic hydrogenated silicon film in environment of active hydrogen and active oxygen, the amount of active oxygen accounts for 4%-99% of the total amount of active hydrogen and active oxygen, or, a nitric hydrogenated silicon film in environment of active hydrogen and active nitrogen, the amount of active nitrogen accounts for 5%-20% of the total amount of active hydrogen and active nitrogen. Sputtering and reactions are separately conducted, Si first deposits on the base body by magnetic controlled Si target sputtering, and then plasmas of active hydrogen and active oxygen/nitrogen react with silicon for oxygenic or nitric SiH.

Provided are methods of forming stacks comprising a substrate and one or more sol-gel layers disposed on the substrate. Also provided are stacks formed by these methods. The sol-gel layers in these stacks, especially outer layers, may have a porosity of less than 1% or even less than 0.5%. In some embodiments, these layers may have a surface roughness (R.sub.a) of less than 1 nanometers. The sol-gel layers may be formed using radiative curing and/or thermal curing at temperatures of between 400° C. and 700° C. or higher. These temperatures allow application of sol-gel layers on new types of substrates. A sol-gel solution, used to form these layers, may have colloidal nanoparticles with a size of less than 20 Angstroms on average. This small size and narrow size distribution is believed to control the porosity of the resulting sol-gel layers.

A flexible displaying substrate includes: a first flexible film layer; a first barrier layer provided on a first surface of the first flexible film layer, and the first barrier layer is a constant-thickness film layer; a second barrier layer provided on one side of the first barrier layer away from the first flexible film layer; and a second flexible film layer is provided between the first barrier layer and the second barrier layer; wherein a surface of the second barrier layer closer to the first flexible film layer is provided with a slot, and a first orthographic projection of the second flexible film layer on the first flexible film layer and a second orthographic projection of the slot on the first flexible film layer at least partially overlap.

A coated glass article including a glass substrate and a coating deposited over the glass substrate. The coating includes a first inorganic metal oxide layer deposited over a major surface of the glass substrate. A second inorganic metal oxide layer is deposited over the first inorganic metal oxide layer. A third inorganic metal oxide layer is deposited over the second inorganic metal oxide layer. A fourth inorganic metal oxide layer is deposited over the third inorganic metal oxide layer. The coated glass article exhibits a total visible light transmittance (Illuminant C) of 40% or more and a visible light reflectance (Illuminant C) of 30% or more.

An apparatus is provided for coating deposition, particularly by chemical vapour deposition, on three-dimensional glass articles such as bottles. The apparatus lends itself to incorporation in a plant for a continuous production process for glass containers.

A low-reflection coated glass sheet of the present invention includes a glass sheet and a low-reflection coating formed on at least a portion of a principal surface of the glass sheet.

The low-reflection coated glass sheet of the present invention maintains a large transmittance gain even when scraping against foreign matters.

The present invention provides low-reflection coating glass in which a dielectric layer having a higher refractive index and a dielectric layer having a lower refractive index are stacked alternately on a glass substrate.

Asymmetrically strengthened glass articles, methods for producing the same, and use of the articles in portable electronic device is disclosed. Using a budgeted amount of compressive stress and tensile stress, asymmetric chemical strengthening is optimized for the utility of a glass article. In some aspects, the strengthened glass article can be designed for reduced damage, or damage propagation, when dropped.

Antireflective nanoparticle coatings and methods of forming the coatings on substrates are disclosed. One method for forming an antireflective coating includes depositing a nanoparticle coating layer on a substrate, wherein the nanoparticle coating layer includes a colloidal solution of nanoparticles and a solidifying material. The solidifying material includes a silica precursor. The method further includes curing the solidifying material to form silica inter-particle connections between adjacent nanoparticles and between at least some of the nanoparticles and the substrate to bind the nanoparticles to each other and to the substrate to form the antireflective coating.
