Abstract:
1. A method for forming a composite film comprising: (a) providing a flexible plastic substrate; and (b) depositing a multi-layered conductive metallic film continuously on the flexible plastic substrate by a thin-film deposition technique, the multi-layered conductive metallic film comprising two layers of indium cerium oxide (InCeO), each InCeO layer having a thickness from about 30 nm to about 45 nm, and a layer of an alloy of silver, palladium, and copper (Ag/Pd/Cu) having a thickness from about 12 nm to about 16 nm and deposited by sputtering a target including 98.0 atomic % silver, 0.5 atomic % palladium, and 1.5 atomic % copper, with the two layers of InCeO surrounding the layer of Ag/Pd/Cu and the composite film having a transmittance of at least about 90% at 550 nm.
