A coated article including a first antireflective (AR) coating supported by a glass substrate, wherein the first coating may include, moving away from the glass substrate: a dielectric first high index layer; a dielectric first low index layer; a dielectric second high index layer; a dielectric second low index layer comprising an oxide of silicon; a dielectric third high index layer comprising an oxide of niobium; a dielectric first medium index layer, wherein the third high index layer comprising the oxide of niobium is located between and directly contacting the second low index layer comprising the oxide of silicon and the first medium index layer; a dielectric third low index layer; and an overcoat layer; wherein the first coating contains no IR reflecting layer based on silver and/or gold; wherein, from the perspective of a viewer of the coated article, the first coating may be configured so that the coated article has a film side reflective ΔE* value of no greater than 3.0 upon heat treatment of at least about 580 degrees C. The ΔE* value(s) may be measured either with a substantially symmetrical/similar AR coating on the other side of the same glass substrate, or absent any AR coating on the other side of the glass substrate.

Heat treatable coated article having antireflective coating(s) on substrate

A low-emissivity (low-E) coating on a substrate (e.g., glass substrate) includes at least first and second infrared (IR) reflecting layers (e.g., silver based layers) that are spaced apart by contact layers (e.g., NiCr based layers), a layer comprising silicon nitride, and an absorber layer of or including a material such as niobium zirconium which may be oxided and/or nitrided. The absorber layer is designed to allow the coated article to realize glass side reflective (equivalent to exterior reflective in an IG window unit when the coating is provided on surface #2 of an IG window unit) silver color. In certain example embodiments, the coated article (monolithic form and/or in IG window unit form) has a low visible transmission (e.g., from 15-45%, more preferably from 22-39%, and most preferably from 24-35%). In certain example embodiments, the coated article may be heat treated (e.g., thermally tempered and/or heat bent).

Silver colored coated article with low-E coating having absorber layer and low visible transmission

A low-emissivity (low-E) coating on a substrate (e.g., glass substrate) includes at least first and second infrared (IR) reflecting layers (e.g., silver based layers) that are spaced apart by contact layers (e.g., NiCr based layers), a layer comprising silicon nitride, and an absorber layer of or including a material such as niobium zirconium which may be oxided and/or nitrided. The absorber layer is designed to allow the coated article to realize glass side reflective (equivalent to exterior reflective in an IG window unit when the coating is on surface #2 of the IG unit) grey color. In certain example embodiments, the coated article (monolithic form and/or in IG window unit form) has a low visible transmission (e.g., from 20-45%, more preferably from 22-39%, and most preferably from 25-37%). In certain example embodiments, the coated article may be heat treated (e.g., thermally tempered and/or heat bent).

Grey colored coated article with low-E coating having absorber layer and low visible transmission

In certain example embodiments, a coated article includes a carbon-doped zirconium based layer before heat treatment (HT). The coated article is heat treated sufficiently to cause the carbon-doped zirconium oxide and/or nitride based layer to result in a carbon-doped zirconium oxide based layer that is scratch resistant and/or chemically durable. The doping of the layer with carbon (C) has been found to improve wear resistance.
