Claim 8:
9. A coated article, comprising:
a substrate;
an underlayer over at least a portion of the substrate comprising a first refractive index material and a second refractive index material, wherein the underlayer is in direct contact with the substrate;
a transparent conductive oxide layer having a top surface and a bottom surface opposite the top surface over at least a portion of the underlayer; and
an embedded film, wherein the embedded film is embedded within the transparent conductive oxide layer, wherein the embedded film is positioned either closer to the top surface or closer to the bottom surface of the transparent conductive oxide layer,
wherein the embedded film comprises a third refractive index material having a refractive index within 10% of the first refractive index material,
wherein the first refractive index material has a refractive index greater than the second refractive index material, and
wherein the underlayer comprises:
a first underlayer film wherein the first underlayer film comprises the first refractive index material; and
a second underlayer film over at least a portion of the first underlayer film wherein the second underlayer film comprises the second refractive index material.
