Abstract:
A coated article includes a low emissivity (low-E) coating on a glass substrate. The low-E coating includes at least one infrared (IR) reflecting layer of a material such as silver, gold, or the like, and at least one high refractive index layer of or including NbBi. The high index layer (e.g., NBBiOx) is designed and deposited so as to be amorphous in the low-E coating, so as to better withstand optional heat treatment (HT) such as thermal tempering. The high index layer may be a transparent dielectric high index layer.
Abstract:
A coated article includes a low emissivity (low-E) coating having at least one infrared (IR) reflecting layer of a material such as silver, gold, or the like, and a plurality of high refractive index dielectric layers of or including a nitride of Zr and Al. In certain example embodiments, the high refractive index dielectric layers of or including a nitride of Zr and Al may be amorphous or substantially amorphous so as to allow the low-E coating to better withstand optional heat treatment (HT) such as thermal tempering. In certain example embodiments, the low-E coating may be used in applications such as monolithic or insulating glass (IG) window unit, vehicle windows, of the like.
Abstract:
A bi-layer seed layer can exhibit good seed property for an infrared reflective layer, together with improved thermal stability. The bi-layer seed layer can include a thin zinc oxide layer having a desired crystallographic orientation for a silver infrared reflective layer disposed on a bottom layer having a desired thermal stability. The thermal stable layer can include aluminum, magnesium, or bismuth doped tin oxide (AlSnO, MgSnO, or BiSnO), which can have better thermal stability than zinc oxide but poorer lattice matching for serving as a seed layer template for silver (111).
Abstract:
Low emissivity panels can include a separation layer of Zn2SnOx between multiple infrared reflective stacks. The low emissivity panels can also include NiNbTiOx as barrier layer. The low emissivity panels have high light to solar gain, color neutral, together with similar observable color before and after a heat treatment process.
Abstract:
A method for making low emissivity panels, including control the composition of a barrier layer formed on a thin conductive silver layer. The barrier structure can include an alloy of a first element having high oxygen affinity with a second element having low oxygen affinity. The first element can include Ta, Nb, Zr, Hf, Mn, Y, Si, and Ti, and the second element can include Ru, Ni, Co, Mo, and W, which can have low oxygen affinity property. The alloy barrier layer can reduce optical absorption in the visible range, can provide color-neutral product, and can improve adhesion to the silver layer.
Abstract:
Disclosed herein are systems, methods, and apparatus for forming low emissivity panels. A first dielectric layer is disposed over a substrate and includes a bi-metal oxide having tin and bismuth or niobium. A seed layer is disposed directly on the first dielectric layer. A reflective layer including silver is disposed directly on the seed layer. A barrier layer is disposed above the reflective layer. The barrier layer includes one of a nickel chromium titanium aluminum alloy or a nickel chromium titanium aluminum oxide. The nickel chromium titanium aluminum alloy or the nickel chromium titanium aluminum oxide includes between about 5% and about 10% by weight nickel, between about 25% and about 30% by weight chromium, between about 30% and about 35% by weight titanium, and between about 30% and about 35% by weight aluminum.
Abstract:
A transparent dielectric composition comprising tin, oxygen and one of aluminum or magnesium with preferably higher than 15% by weight of aluminum or magnesium offers improved thermal stability over tin oxide with respect to appearance and optical properties under high temperature processes. For example, upon a heat treatment at temperatures higher than 500 C, changes in color and index of refraction of the present transparent dielectric composition are noticeably less than those of tin oxide films of comparable thickness. The transparent dielectric composition can be used in high transmittance, low emissivity coated panels, providing thermal stability so that there are no significant changes in the coating optical and structural properties, such as visible transmission, IR reflectance, microscopic morphological properties, color appearance, and haze characteristics, of the as-coated and heated treated products.

Abstract:
A coated article includes a low emissivity (low-E) coating having at least one infrared (IR) reflecting layer of a material such as silver, gold, or the like, and at least one high refractive index layer of or including titanium oxide and at least one additional metal. A doped titanium oxide layer(s) is designed and deposited in a manner so as to be amorphous or substantially amorphous (as opposed to crystalline) in the low-E coating, so as to better withstand optional heat treatment (HT) such as thermal tempering and reduce haze. The high index layer may be a transparent dielectric high index layer in preferred embodiments, which may be provided for antireflection purposes and/or color adjustment purposes, in addition to having thermal stability.
