Abstract
A method is provided for color tuning a plasmonic device with a color tunable electronic skin. A plasmonic electronic skin is used, including a first substrate, a plasmonic structure, an electrically conductive transparent first electrode layer, an electrically conductive transparent second electrode layer, and a polymer-networked liquid crystal (PNLC) layer interposed between the first and second transparent electrode layers. In response to receiving a color tuning voltage, a full visible spectrum incident light, and a PNLC switch voltage, the plasmonic structure generates a first primary color. A primary color exhibits a single wavelength peak with a spectral full width at half magnitudes (FWHMs) in the visible spectrum of light. In response to receiving the PNLC switch voltage between the first and second electrode layers, the PNLC layer passes incident light.
