A coated article is provided with an absorbing layer(s). The coating is, in certain example embodiments, designed so that significant changes in visible transmission can be made by adjusting thickness of the absorbing layer without significantly affecting certain other characteristics such as certain color values. Such coated articles may be used monolithically or in the context of insulating glass (IG) units in different embodiments of this invention, and may or may not be heat treated.

Coated article with absorbing layer

A coated article that can be used in applications such as insulating glass (IG) units, so that resulting IG units can achieve high visible transmission of at least 70% (e.g., when using clear glass substrates from 1.0 to 3.5 mm thick), combined with at least one of: (a) SHGC no greater than about 0.45, more preferably no greater than about 0.40; (b) SC no greater than about 0.49, more preferably no greater than about 0.46; (c) chemical and/or mechanical durability; (d) neutral transmissive color such that transmissive a* is from &#x2212;5.0 to 0 (more preferably from &#x2212;3.5 to &#x2212;1.5), and transmissive b* is from &#x2212;2.0 to 4.0 (more preferably from 1.0 to 3.0); and (e) neutral reflective color from the exterior of the IG unit (i.e., Rg/R) such that reflective a* is from &#x2212;3.0 to 2.0 (more preferably from &#x2212;2.0 to 0.5), and reflective b* is from &#x2212;5.0 to 1.0 (more preferably from &#x2212;4.0 to &#x2212;1.0). In certain example non-limiting embodiments, coated articles herein comprise: substrate/TiO/ZnO/Ag/NiCrO/SnO/ZnO/Ag/NiCrO/SnO/SiN.

Coated article with high visible transmission and low emissivity

A coated article is provided so as to have a fairly high visible transmission (TY or T) to sheet resistance (R) ratio (i.e., a ratio T/R). The higher this ratio, the better the coated article's combined functionality of providing for both good solar performance (e.g., ability to reflect and/or absorb IR radiation) and high visible transmission. In certain example embodiments, coated articles herein may be heat treatable. Coated articles herein may be used in the context of insulating glass (IG) window units, architectural or residential monolithic window units, vehicle window units, and/or the like.

Heat treatable coated article with zinc oxide inclusive contact layer(s)

A heat treatable coated article (e.g., vehicle windshield, IG unit, etc.) is provided with a dual-silver low-E coating. Before and/or after heat treatment (HT), the coating and/or coated article has a visible transmittance of at least 70%, more preferably at least 75%. Moreover, the coating and/or coated article is designed so as to have approximately the same color when viewed over a wide range of viewing angles. In certain embodiments, at least one contact layer (e.g., of or including NiCrO) that contacts an infrared (IR) reflecting layer (e.g., Ag) is oxidation graded so that it progressively becomes less oxidized through its thickness as it nears the IR reflecting layer. In still other embodiments, a Si-rich silicon nitride layer(s) may be utilized to reduce haze.

Heat treatable low-E coated articles and methods of making same

Heat treatable coated article with high ratio of transmission over sheet resistance

A sputter coated article is provided with improved mechanical durability (e.g., pre-HT scratch resistance) and/or thermal stability by sputtering at least one Ag inclusive layer in an atmosphere including at least Ogas. For instance, in certain example embodiments an Ag inclusive target may be sputtered in an atmosphere including a combination of Ar and Ogas. In certain embodiments, this enables the resulting AgOinfrared (IR) reflecting layer to better adhere to adjacent contact layer(s).

A coated article is provided so as to have fairly neutral a* and/or b* color values at high viewing angles such as 45 and/or 60 degrees off-axis. In certain example embodiments, the neutral a* and/or b* values at high viewing angles (VA) are caused by lessening the thickness of a bottom titanium oxide layer. Coated articles herein may be used in the context of insulating glass (IG) window units, or in other suitable applications.

Method of making coated article with high visible transmission and low emissivity

A sputter coated article is provided with improved mechanical durability (e.g., pre-HT scratch resistance) and/or thermal stability by sputtering at least one Ag inclusive layer in an atmosphere including at least O gas. For instance, in certain example embodiments an Ag inclusive target may be sputtered in an atmosphere including a combination of Ar and O gas. In certain embodiments, this enables the resulting AgO infrared (IR) reflecting layer to better adhere to adjacent contact layer(s).
