Full Color Generation Using Silver Tandem Nanodisks.

摘要: Plasmonic effects associated with metallic nanostructures have been widely studied for color generation. It became apparent that highly saturated and bright colors are hard to obtain, very small need be fabricated. To address this issue, in study, we employ metal–insulator–metal sandwich nanodisks support enhanced in-phase electric dipole modes, which blue-shifted respect a single metal disk. The blue shift enables the generation of short wavelength larger nanostructures. radiation modes hybridize Wood’s anomaly periodic structures, creating narrow high-resonance peaks reflection deep valleys transmission spectra, thus producing vivid complementary both cases. Full can achieved by tuning radius periodicity arrays. Good agreement between simulations experiments is demonstrated analyzed CIE1931, sRGB, HSV spaces. presented method has p...
