Plasmonic Color Switching by a Combination Device with Nematic Liquid Crystals and a Silver Nanocube Monolayer.

ABSTRACT: We experimentally demonstrated electrical plasmonic color modulation by combining a nematic-phase liquid crystal (LC) layer and a silver nanocube (AgNC) monolayer. The color modulation LC/AgNC device was fabricated by filling LCs with negative dielectric anisotropy onto a densely assembled AgNC monolayer. The transmitted light color through the LC/AgNC device was modulated between green and magenta by applying voltages of 0-15 V. The peaks and dips in the transmission spectrum of the LC/AgNC device at wavelengths of 500-600 nm were switched with voltage. The switching effect of light transmission in the green region was achieved by overlapping the plasmon resonance of the AgNC monolayer and multiple transmittance peaks caused by the birefringence of the LC layer. In addition, the color inv
