摘要：

Light-driven plasmonic color filters are demonstrated by integrating gold annular aperture arrays with photoresponsive liquid crystals (LCs). Upon photoirradiation, a nematic-isotropic phase transition of the LCs arises from the trans-cis photoisomerization of photochromic LCs. As a consequence, the effective refractive index experienced by the impinging light changes, modulating the transmission intensity. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
