Coated article having low-E coating with absorber layer(s)

摘要

A coated article is provided, having a coating supported by a glass substrate where the coating includes at least one color and/or reflectivity-adjusting absorber layer. The absorber layer(s) allows color tuning, and reduces the glass side reflection of the coated article and/or allows sheet resistance of the coating to be reduced without degrading glass side reflection. In certain example embodiments the absorber layer is provided between first and second dielectric layers which may be of substantially the same material and/or composition. In certain example embodiments, the coated article is capable of achieving desirable transmission, together with desired color, low reflectivity, and low selectivity, when having only one infrared (IR) reflecting layer of silver and/or gold. Coated articles according to certain example embodiments of this invention may be used in the context of insulating glass (IG) window units, monolithic windows, or the like.

主权项

1. A bronze colored coated article comprising a coating supported by a glass substrate, the coating comprising at least the following layers moving away from the glass substrate:
a first dielectric layer comprising silicon nitride; a first contact layer; an IR reflecting layer comprising silver, wherein the coating has only one IR reflecting layer comprising silver; a second contact layer, the first and second contact layers each directly contacting the IR reflecting layer; a second dielectric layer comprising silicon nitride; wherein at least one of the first and second dielectric layers comprising silicon nitride is split by an absorber layer comprising one or more of: Ni, Cr, NiCr, Nb, Zr, NbZr, Si, Ti, Zn, Sn, Cu, Al, V, Mn, Mo, Pd, Ta, W, In, InSn, and stainless steel so as to have first and second spaced apart layer portions comprising silicon nitride with the absorber layer comprising one or more of: Ni, Cr, NiCr, Nb, Zr, NbZr, Si, Ti, Zn, Sn, Cu, Al, V, Mn, Mo, Pd, Ta, W, In, InSn, and stainless steel directly therebetween, the absorber layer being provided so that coated article is bronze colored; and wherein the coated article has a visible transmission of no greater than 50% and bronze color by way of a*g color value of from +1.0 to +2.5 and a glass side visible reflectance (Y) of from 9-13%, and wherein the coated article is able to achieve these characteristics when having only one IR reflecting layer comprising silver.
