Abstract
The present invention is directed to coated articles. A substrate is coated with an underlayer having at a first underlayer film made of a first high refractive index material. A transparent conductive oxide layer over at least a portion of the underlayer. An embedded film is embedded within the transparent conductive oxide layer wherein the embedded film comprises a second high refractive index material.
Claims20
A coated article comprising
- a substrate,
- an underlayer over at least a portion of the substrate, the underlayer comprising
- a first underlayer film wherein the first underlayer film comprises a first refractive index material, wherein the first underlayer film is in direct contact with the substrate and wherein the first refractive index material comprises zinc, and
- a second underlayer film over at least a portion of the first underlayer film wherein the second underlayer film comprises a second refractive index material, and wherein the first refractive index material has a refractive index greater than the second refractive index material,
- a transparent conductive oxide layer over at least a portion of the underlayer and
- an embedded film embedded within the transparent conductive oxide layer wherein the embedded film comprises a third refractive index material, and wherein the third refractive index material has a refractive index greater than the second refractive index material.
