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 coated article is provided so as to include a low-E (low emissivity) coating having an infrared (IR) reflecting layer(s) of or including a material such as silver (Ag), which is provided between a pair of contact layers. The low-E coating includes an overcoat having at least one layer of or including zirconium oxide and/or a substantially metallic layer. The overcoat has been found to improve the durability of the coating without significantly sacrificing desired optical characteristics. Such coated articles may be used in the context of windows.
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:
A coated article includes a coating, such as a low emissivity (low-E) coating, supported by a substrate (e.g., glass substrate). The coating includes at least one dielectric layer including tin oxide that is doped with another metal(s). The coating may also include one or more infrared (IR) reflecting layer(s) of or including material such as silver or the like, for reflecting at least some IR radiation. In certain example embodiments, the coated article may be heat treated (e.g., thermally tempered, heat bent and/or heat strengthened). Coated articles according to certain example embodiments of this invention may be used in the context of windows, including monolithic windows for buildings, IG windows for buildings, etc.

An IG window unit includes a coating supported by a glass substrate. The coating includes at least the following on the glass substrate moving from the glass substrate outwardly: at least one dielectric layer; a layer comprising zinc oxide; an infrared (IR) reflecting layer comprising silver; a layer comprising an oxide of Ni and/or Cr; an overcoat comprising a layer comprising tin oxide located over the oxide of Ni and/or Cr and a layer comprising silicon nitride.
Abstract:
A low-E coating supported by a glass substrate, the coating from the glass substrate outwardly including at least the following layers: a dielectric layer of or including silicon nitride; a high index layer having a refractive index of at least 2.1; another dielectric layer of or including silicon nitride; a layer comprising zinc oxide; an infrared (IR) reflecting layer, wherein the coating includes only one IR reflecting layer; and an overcoat including (i) a layer comprising tin oxide and (ii) a layer comprising silicon nitride located over and contacting the layer comprising tin oxide. An IG unit including the coating may have a visible transmission of at least 70%.
Abstract:
An insulating glass (IG) window unit includes first and second substrates, and a low-emissivity (low-E) coating supported by one of the substrates. The low-E coating has two silver based infrared (IR) reflecting layers and allows the IG window unit to realize an increased SHGC to U-value ratio, and an increased thickness ratio of an upper silver based layer of the coating to a bottom silver based layer of the coating. The low-E coating is designed to have a low film-side reflectance, so that for example when the low-E coating is used on surface number three of an IG window unit the IG window unit can realize reduced visible reflectance as viewed from the outside of the building on which the IG window unit is mounted or is to be mounted.
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:
Example embodiments of this invention relate to a coated article including an infrared (IR) reflecting layer of a material such as silver or the like, for use in an insulating glass (IG) window unit for example. In certain example embodiments, the coating is a single-silver type coating, and includes an overcoat including an uppermost layer of or including silicon nitride and a layer of or including tin oxide immediately under and contacting the silicon nitride based overcoat. In certain example embodiments, the thicknesses of the silicon nitride based overcoat and the tin oxide based layer are balanced (e.g., substantially equal, or equal plus/minus about 10%). It has surprisingly been found that such balancing results in an improvement in thermal cycling performance and improved mechanical durability. In certain example embodiments, the coating may realize surprisingly good substantially neutral film side reflective coloration, and may achieve an improved visible transmission, SHGC ratio and low U-values. Moreover, in certain example embodiments, stress in the overcoat of the coating may be reduced by reducing nitrogen gas flow (N2 ml/kW) and cathode power during a sputter-deposition process, thereby further improving thermal cycling performance.
