Coated article with low-E coating including zinc oxide inclusive layer(s) with additional metal(s)

摘要

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 zinc 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.

主权项

1. A coated article including a low-E coating on a glass substrate, the coating comprising:
first and second infrared (IR) reflecting layers comprising silver on the glass substrate a contact layer over and directly contacting the first IR reflecting layer; a dielectric stack provided between the first and second IR reflecting layers comprising silver, and provided over the contact layer; wherein the dielectric stack between the IR reflecting layers comprising silver comprises first and second dielectric layers each comprising an oxide of one or more of: ZnCuNi, ZnNi, ZnNiAl, and ZnNiMg; wherein a layer comprising silicon nitride is located between and contacting the first and second layers comprising an oxide of one or more of: ZnCuNi, ZnNi, ZnNiAl, and ZnNiMg; and another contact layer located under and directly contacting the second IR reflecting layer.
