Abstract: A coated article is provided with at least one functional layer, such as an infrared (IR) reflecting layer(s) of or including silver and/or gold. A dielectric and substantially transparent seed layer is provided under and directly contacting the functional layer. In certain example embodiments, the seed layer includes an oxide of zinc and boron for increasing the hardness of the layer and thus improving durability of the overall coating. The seed layer may further include aluminum and/or gallium, for enhancing the electrical properties and/or reducing the stress in the resulting coating. The seed layer may be deposited by a substantially metallic target in the presence of oxygen in certain examples.
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 low-e insulating glass unit has a suspended, coated IR reflecting polymer sheet under tension, e.g. from heat shrinkage. The polymer sheet is coated with a multilayer stack of dielectric and metallic layers, including at least one silver layer deposited upon a zinc oxide seed layer that is at most 15 nm thickness. The use of zinc oxide ensures good seeding for high quality silver layer growth, thereby providing low emissivity. The thinness of the zinc oxide ensures that it resists cracking when the polymer sheet is tensioned.
