  • Patent number: 11279651
    Abstract: A low-E coating has good color stability (a low ?E* value) upon heat treatment (HT). Thermal stability may be improved by the provision of an as-deposited crystalline or substantially crystalline layer of or including zinc oxide, doped with at least one dopant (e.g., Sn), immediately under an infrared (IR) reflecting layer of or including silver; and/or by the provision of at least one dielectric layer of or including an oxide of zirconium. These have the effect of significantly improving the coating's thermal stability (i.e., lowering the ?E* value). An absorber film may be designed to adjust visible transmission and provide desirable coloration, while maintaining durability and/or thermal stability. The dielectric layer (e.g., of or including an oxide of Zr) may be sputter-deposited so as to have a monoclinic phase in order to improve thermal stability.

  • Patent number: 11027527
    Abstract: 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).

  • Patent number: 10830933
    Abstract: Certain example embodiments of this invention relate to coated articles having a metamaterial-inclusive layer, coatings having a metamaterial-inclusive layer, and/or methods of making the same. Metamaterial-inclusive coatings may be used, for example, in low-emissivity applications, providing for more true color rendering, low angular color dependence, and/or high light-to-solar gain. The metamaterial material may be a noble metal or other material, and the layer may be made to self-assemble by virtue of surface tensions associated with the noble metal or other material, and the material selected for use as a matrix. An Ag-based metamaterial layer may be provided below a plurality (e.g., 2, 3, or more) continuous and uninterrupted layers comprising Ag in certain example embodiments. In certain example embodiments, barrier layers comprising TiZrOx may be provided between adjacent layers comprising Ag, as a lower-most layer in a low-E coating, and/or as an upper-most layer in a low-E coating.

  • Patent number: 10494859
    Abstract: Certain example embodiments of this invention relate to insulating glass (IG) units including three substantially parallel spaced apart glass substrates, wherein at least two of the surfaces include low-emissivity (low-E) coatings and at least some of the non-low E coated surfaces have antireflective (AR) coatings disposed thereon. In certain example embodiments, low-E coatings are provided on the second and fifth surfaces of the IG unit, and each internal surface of the IG unit that does not support a low-E coating does support an AR coating. Additional AR coatings may be provided on one or both of the outermost surfaces in certain example embodiments. In some cases, the center substrate need not be heat treated because of the reduced absorption enabled by providing the low-E coatings on the two outermost substrates, as well as the reduced heat accumulation in the center lite itself and in the two adjacent spacers.
