摘要:
A heat-treatable dichroic mirror, comprising a transparent substrate having a glass transition temperature in the range of 650-800° C., and a plurality of sputtered films carried on said substrate and forming at least two pairs of contiguous films in which the films of each pair have disparate refractive indices differing by at least about 0.2 so as to provide between them a reflective interface. The films include an oxide of a metal such as titanium, a second film comprising an oxidizable metal or semi-metal such as silicon, and a protective overcoat of a thickness and composition sufficient to substantially prevent permeation of oxygen therethrough when heat treated at said glass transition temperature. The mirror, after said heat treatment, exhibits a transmittance of at least 24% in the wavelength range of 550-650 nm, a reflectance of at least 45%, and a haze of not greater than about 1%.

摘要:
A heat formable mirror is formed by sputter depositing upon a sheet such as glass a reflective coating utilizing a base layer of silicon or a combination of silicon and stainless steel films, a reflective layer formed of a reflective metallic film such as titanium or aluminum, and a protective layer comprising preferably silicon nitride. The resulting mirror can be heat formed at elevated temperatures to form a curved mirror having a reflective coating free of objectionable defects.

摘要:
A photovoltaic element for photovoltaic applications includes a transparent substrate having a first side and a second side. A transparent electrically conductive oxide is disposed over the first side of the transparent substrate. Similarly, a hydrophilic oxide coating is disposed over and contacts the transparent electrically conductive oxide. Finally, a removable protective coating is disposed over the hydrophilic oxide coating.
摘要:
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.

The invention provides a substrate bearing a low-maintenance coating. The coating includes two films: a first film comprising silica (e.g., silicon dioxide) and a second film comprising titania (e.g., titanium dioxide). Preferably, both films are provided within particular thickness ranges. The invention also provides methods of depositing such coatings.
摘要:
A sheet-like pane bearing a low-maintenance coating on one surface and a low-emissivity coating on the opposite surface, wherein one of the low-maintenance coating and the low-emissivity coating has a single surface reflectivity of less than 3 times, and more than one-third, that of the other coating.
摘要:
A plasma enhanced chemical vapor deposition method is provided for depositing an oxide film onto a substrate surface. Deposition is achieved even onto a surface of a glass or other relatively non-receptive substrate. A sub-film is deposited under plasma enhanced chemical vapor deposition conditions more strongly favoring deposition, followed by deposition of the desired oxide film under second plasma enhanced chemical vapor deposition conditions less strongly favoring deposition. High quality oxide films can be achieved by deposition at second plasma enhanced chemical vapor deposition conditions only marginally favoring deposition over etching.
