ABSTRACT:
The invention provides a substrate bearing a low-emissivity coating. The low-emissivity coating comprises at least one graded film region. In certain embodiments, at least one graded film region is provided between the two infrared-reflective layers of a double-type low-emissivity coating. The graded film region has a substantially continuously decreasing concentration of a first dielectric material and a substantially continuously increasing concentration of a second dielectric material. Also provided are methods of depositing such low-emissivity coatings and substrates bearing these coatings.
