摘要:
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).

摘要:
Disclosed herein are systems, methods, and apparatus for forming low emissivity panels. In some embodiments, a partially fabricated panel may be provided that includes a substrate, a reflective layer formed over the substrate, and a barrier layer formed over the reflective layer such that the reflective layer is formed between the substrate and the barrier layer. The barrier layer may include a partially oxidized alloy of three or more metals. A first interface layer may be formed over the barrier layer. A top dielectric layer may be formed over the first interface layer. The top dielectric layer may be formed using reactive sputtering in an oxygen containing environment. The first interface layer may prevent further oxidation of the partially oxidized alloy of the three or more metals when forming the top dielectric layer. A second interface layer may be formed over the top dielectric layer.

Disclosed herein are systems, methods, and apparatus for forming a low emissivity panel. In various embodiments, a partially fabricated panel may be provided. The partially fabricated panel may include a substrate, a reflective layer formed over the substrate, and a top dielectric layer formed over the reflective layer such that the reflective layer is formed between the substrate and the top dielectric layer. The top dielectric layer may include tin having an oxidation state of +4. An interface layer may be formed over the top dielectric layer. A top diffusion layer may be formed over the interface layer. The top diffusion layer may be formed in a nitrogen plasma environment. The interface layer may substantially prevent nitrogen from the nitrogen plasma environment from reaching the top dielectric layer and changing the oxidation state of tin included in the top dielectric layer.
摘要:
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.

摘要:
Low emissivity coated panels can be fabricated using a base layer having a low refractive index layer on a high refractive index layer. The low refractive index layer can have refractive index less than 1.5, and can include Mg F2, CaF2, SiO2, or BO. The high refractive index layer can have refractive index greater than 2.3, and can include TiOx, NbOx, or BiOx. The multilayer base structure can allow color tuning with enhanced transmission, for example, as compared to similar structures having single layer base layer.

The top dielectric layer may include a ternary metal oxide, such as zinc tin aluminum oxide. The top dielectric layer may also include aluminum. The concentration of aluminum may be between about 1 atomic % and 15 atomic % or between about 2 atomic % and 10 atomic %. An atomic ratio of zinc to tin in the top dielectric layer may be between about 0.67 and about 1.5 or between about 0.9 and about 1.1.
