Abstract:
Certain examples relate to a method of making an antireflective (AR) coating supported by a glass substrate. The anti-reflection coating may include porous metal oxide(s) and/or silica, and may be produced using a sol-gel process. The pores may be formed and/or tuned in each layer respectively in such a manner that the coating ultimately may comprise a porous matrix, graded with respect to porosity. The gradient in porosity may be achieved by forming first and second layers using one or more of (a) nanoparticles of different shapes and/or sizes, (b) porous nanoparticles having varying pore sizes, and/or (c) compounds/materials of various types, sizes, and shapes that may ultimately be removed from the coating post-deposition (e.g., carbon structures, micelles, etc., removed through combustion, calcination, ozonolysis, solvent-extraction, etc.), leaving spaces where the removed materials were previously located.
Abstract:
The invention relates to a transparent glass substrate having a coating including, in order: a first reflected color neutralization layer; a low-emissivity second layer essentially made up of SnO 2 :F and having a thickness between 455 and 800 nm; and a third layer that is essentially made up of SiO x , x being less than or equal to 2, and has a thickness between 40 and 65 nm or between 140 and 180 nm. The invention also relates to a double glass sheet and a triple glass sheet, manufactured from such a glass substrate, and to a window comprising said glass sheets.
Abstract:
The invention is drawn to a method of producing a transparent diffusive OLED substrate comprising the following successive steps: (a) lapping one face or both faces of a flat translucent glass substrate with an abrasive slurry, so as to obtain a flat glass substrate with at least one roughened surface having a roughness profile with an arithmetical mean deviation R a of between 0.1 µm and 2.0 µm, preferably between 0.15 µm and 1.5 µm, more preferably between 0.2 and less than 1.0 µm and most preferably of between 0.25 µm and 0.8 µm, (b) coating the roughened surface or one of the roughened surfaces with a high index glass frit having a refractive index of at least 1.7, preferably of between 1.7 and 2.2, the amount of the high index glass frit being sufficient to completely cover the roughness profile of the roughened surface after melting of said frit ; (c) heating the coated substrate to a temperature above the melting temperature of the high index glass frit and below the softening temperature of the underlying substrate, so as to form high index enamel on one of the roughened surfaces.
Abstract:
A thermochromic substrate and a pair-glass with a thermochromic thin film, which increases the efficiency with which solar energy is transmitted and blocked. The thermochromic substrate includes a base substrate, a thermochromic thin film coating the base substrate, and a high-refractivity thin film coating the thermochromic thin film. The high-refractivity thin film shifts the reference wavelength in the infrared range, at which the variance in the transmittance due to the phase transition does not exceed 0, to a shorter wavelength. The efficiency with which solar energy is transmitted and blocked is increased, thereby decreasing the load of cooling and heating a building.
Abstract:
A glass substrate is provided having a major surface on which there is a coating comprising a transparent conductive oxide film. The TCO film may comprise aluminum-doped zinc aluminum oxide ("AZO") or tin-doped indium oxide ("ITO"). When the coated glass substrate is heat-treated, the coating exhibits desirable sheet resistance and absorption values. In some cases, the coating comprises a first transparent dielectric film, a second transparent dielectric film, a transparent conductive oxide film comprising AZO or ITO, and a third transparent dielectric film.
Abstract:
A thermochromic substrate and a method of manufacturing the same, in which the crystallinity of a thermochromic layer can be improved. The method includes the steps of forming a pre-thermochromic layer on a glass substrate by coating the glass substrate with pure vanadium, forming a seed layer by heat-treating the pre-thermochromic layer, and forming a thermochromic layer by coating the heat-treated seed layer with a vanadium dioxide (VO 2 ) thin film.
