Title: COATED ARTICLE HAVING LOW-E COATING WITH IR REFLECTING LAYER(S) AND YTTRIUM INCLUSIVE HIGH INDEX NITRIDED DIELECTRIC 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 at least one yttrium (Y) inclusive high index nitrided dielectric layer. In certain example embodiments, the yttrium inclusive high index nitrided dielectric layer(s) may be of or include one or more of YZrSiAlN, YZrSiN, YSiN, and/or YSiAlN. The high index layer may be a transparent dielectric high index layer, with a high refractive index (n) and low k value, in preferred embodiments and may be provided for antireflection purposes and/or visible transmission purposes, and/or for improving thermal stability. In certain example embodiments, the low-E coating may be used in applications such as monolithic or insulating glass (IG) window units, vehicle windows, or the like.
