Patent number: 10023494Abstract: 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.Type: GrantFiled: July 8, 2016Date of Patent: July 17, 2018Assignees: Centre Luxembourgeois de Recherches pour le Verre et la Ceramique S.A.

Patent number: 10011524Abstract: Certain example embodiments relate to coated articles with sequentially activated low-E coatings, and/or methods of making the same. In certain example embodiments, one or more infrared reflecting layers is/are activated via a non-equilibrium preconditioning activation that uses photons with specific frequencies/frequency ranges, followed by a more equilibrium thermal activation. The preconditioning activation aids in rearranging the silver atoms to energetically favorable positions, while helping to avoid their unwanted agglomeration. The more equilibrium thermal stage of activation aids in aligning the chemical potentials of the layers of the stack and in further densification of the preconditioned silver layer. Doing so, in turn, helps to reduce the likelihood of stresses building-up in the coating, the formation of point and dimensional defects, other unwanted efficiency-reducing phenomena, and/or the like.Type: GrantFiled: June 19, 2015Date of Patent: July 3, 2018Assignees: Guardian Glass, LLC, Centre Luxembourgeois de Recherches Pour le Verre et la Ceramique (C.R.V.C.)

Patent number: 9802860Abstract: Certain example embodiments relate to a coated article including at least one infrared (IR) reflecting layer of a material such as silver or the like in a low-E coating, and methods of making the same. In certain cases, at least one layer of the coating is of or includes nickel and/or titanium (e.g., NixTiyOz). The provision of a layer including nickel titanium and/or an oxide thereof may permit a layer to be used that has good adhesion to the IR reflecting layer, and reduced absorption of visible light (resulting in a coated article with a higher visible transmission). When a layer including nickel titanium oxide is provided directly over and/or under the IR reflecting layer (e.g., as a barrier layer), this may result in improved chemical and mechanical durability. Thus, visible transmission may be improved if desired, without compromising durability; or, durability may simply be increased.Type: GrantFiled: September 18, 2013Date of Patent: October 31, 2017Assignees: Guardian Glass, LLC, Centre Luxembourgeois de Recherches pour le Verre et la Ceramique S.A.
