Abstract |
Plasmonic color generation offers several advantages but is also limited by the cost and availability of noble metals like gold. In this work we present color-tuneable metasurfaces with high chromaticity and reflectivity consisting of an aluminum mirror, a dielectric spacer and a plasmonic nanohole array in copper. Copper is shown to be an excellent alternative to gold when properly protected from oxidation and makes it possible to generate a wide RGB gamut covering 27% of the standard RGB. By patterning the metasurfaces into microscale pixel triplets, color photos can be well reproduced with high resolution over wafer-sized areas. Further, we demonstrate active modulation of the reflected intensity using an electrochromic conductive polymer deposited on top of the nanostructures by screen printing. This technology opens up for ultrathin and flexible reflective displays in full color, i.e. plasmonic electronic paper, compatible with large-scale sustainable production. |
