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 high refractive index dielectric multilayer film. The high index dielectric multilayer film may be of or include a first high index layer of or including ZrSiN and/or ZrSiAlN, and a second high index layer of or including titanium oxide (e.g., TiO2). The first high index layer of or including ZrSiN and/or ZrSiAlN may be amorphous or substantially amorphous, and the second high index layer of or including titanium oxide may be substantially crystalline 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.
