Abstract
A method of forming a structural color filter includes: depositing a first metal layer on a surface of a substrate by applying an electric potential to the substrate; depositing a first dielectric layer on the first metal layer by contacting the first metal layer with a second electrolyte; and depositing a second metal layer on the first dielectric layer. The surface of the substrate is in contact with a first electrolyte; the first electrolyte comprises a first precursor, an electrochemical reaction of the first precursor at the surface of the substrate is driven by the electric potential; the depositing the first metal layer on the surface of the substrate is performed at a temperature of less than or equal to 50° C. The second electrolyte comprises a second precursor of a first dielectric material of the first dielectric layer.
