coated article that has a low emissivity coating with a reflective iv layer (or layers) and a high-index nitrous dielectric layer including yttrium

摘要

a coated article includes a low emissivity (low e) coating having at least one infrared reflective layer (ir) of a material such as silver, gold or the like and at least one high index nitrite dielectric layer including yttrium (y). in certain exemplary embodiments, the high-index nitrite dielectric layer (s) with yttrium may be or include one or more of yzrsialn, yzrsin, ysin and / or ysialn. the high-index layer may be a high-index transparent dielectric layer, with a high refractive index (n) and a low k value, in preferred embodiments, and may be provided for anti-reflective and / or visible transmission purposes and / or to improve thermal stability. in certain exemplary embodiments, the coating is low and can be used in applications such as monolithic or insulating glass (ig) window units, vehicle windows or the like.
