A coated article includes a coating, such as a low emissivity (low-E) coating, supported by a substrate (e.g., glass substrate). The coating includes at least one dielectric layer including tin oxide that is doped with another metal(s). The coating may also include one or more infrared (IR) reflecting layer(s) of or including material such as silver or the like, for reflecting at least some IR radiation. In certain example embodiments, the coated article may be heat treated (e.g., thermally tempered, heat bent and/or heat strengthened). Coated articles according to certain example embodiments of this invention may be used in the context of windows, including monolithic windows for buildings, IG windows for buildings, etc.

The low-reflection coating of the present invention is adapted to be provided on at least one principal surface of a substrate. The low-reflection coating is a porous film having a thickness of 80 to 800 nm, the porous film including: fine silica particles being solid and spherical and having an average particle diameter of 80 to 600 nm; and a binder containing silica as a main component and containing a hydrophobic group, the fine silica particles being bound by the binder. The low-reflection coating contains 35 to 70 mass % of the fine silica particles, 25 to 64 mass % of the silica of the binder, and 0.2 to 10 mass % of the hydrophobic group of the binder. The low-reflection coating produces a transmittance gain of 1.5% or more when provided on the substrate.

Insulated glazing units comprising first and second sheets of glazing material with a low pressure space there between are described. The major surface of the second sheet of glazing material not facing the low pressure space has a low emissivity coating comprising at least one layer of fluorine doped tin oxide thereon. There is a first anti-iridescence coating between the low emissivity coating and the second sheet of glazing material. Also described are insulated glazing units comprising three (first, second and third) sheets of glazing material with a low pressure space between first and second sheets of glazing material, and a second space between the first and third sheets of glazing material. There is a low emissivity coating on one or both major surfaces facing the low pressure space. The third sheet of glazing material has a low emissivity coating on both opposed major surfaces thereof.

A method of reducing the emissivity of a coated glass article includes the following steps in sequence: (a) forming a coated glass article, the coated glass article comprising a glass substrate and a coating formed on the glass substrate, the coating having a first layer deposited over the glass substrate and a second layer, the second layer being provided between the first layer and the glass substrate, wherein the coated glass article exhibits a first emissivity; and (b) heating the coated glass article in an environment set to a predetermined temperature and for a predetermined period of time. After step (b), the coated glass article exhibits a second emissivity, the second emissivity being less than the first emissivity.

A window structure includes a metal layer that transmits microwave signals and reflects infrared signals. A microwave signal is a signal that has a frequency in the microwave spectrum of frequencies (a.k.a. the microwave frequency spectrum). The microwave frequency spectrum extends from 300 megahertz (MHz) to 300 gigahertz (GHz). An infrared signal is a signal that has a frequency in the infrared spectrum of frequencies (a.k.a. the infrared frequency spectrum, which extends from 300 GHz to 430 terahertz (THz)). The metal layer may be a discontinuous metal layer that's an electrically discontinuous metal layer and/or a physically discontinuous metal layer.
