Coated article with IR reflecting layer(s) and method of making same
A coated article is provided with at least one infrared (IR) reflecting layer. The IR reflecting layer may be of silver or the like. In certain example embodiments, a titanium oxide layer is provided over the IR reflecting layer, and it has been found that this surprisingly results in an IR reflecting layer with a lower specific resistivity (SR) thereby permitting thermal properties of the coated article to be improved.

Coated article with low-E coating having absorbing layers for low film side reflectance and low visible transmission
Absorbing layers of a low-emissivity (low-E) coating are designed to cause the coating to have a reduced film side reflectance which is advantageous for aesthetic purposes. In certain embodiments, the absorbing layers are metallic or substantially metallic (e.g., NiCr or NiCrN.sub.x) and are positioned in order to reduce or prevent oxidation of the absorbing layers during optional heat treatment (e.g., thermal tempering, heat bending, and/or heat strengthening). Coated articles according to certain example embodiments of this invention may be used in the context of insulating glass (IG) window units, other types of windows, etc.
Multilayer heat rejection coating
There is provided a multilayer coating comprising a plurality of layers comprising a) one or more layers of an elemental transition metal; b) one or more layers of an elemental metalloid; and c) two or more layers of an oxide; characterized in that the transition metal and metalloid layers are between the oxide layers and the plurality of layers does not need to contain an additional transparent conductive film (TCF). The multilayer coatings show high transparency in the visible light range combined with heat shielding without the need of transparent conductive oxide which have been previously used to achieve these properties. The multilayers can be produced with conventional physical vapor deposition methods on glass and polymer substrates. The coatings may therefore be used for applications on windows, plastic sheets and window shields. The invention relates also to the process for making the multilayer coatings, articles comprising them and their use in building and other applications.
