Up Scalable Full Colour Plasmonic Pixels with Controllable Hue, Brightness and Saturation

Abstract It has long been the interests of scientists to develop ink free colour printing technique using nano structured materials inspired by brilliant colours found in many creatures like butterflies and peacocks. Recently isolated metal nano structures exhibiting preferential light absorption an...
