Fig 11 The plasmon excititation modes of the precise assemblies and the application in display (a) Scattering spectra of a single gold NR at different polarization angles. (b, c) Dark-field images at 0° (left) and 90° (right) polarization angles of the letters "A" and "u" assembled from gold NR arrays with perpendicular orientations. Insets: corresponding scanning electron microscope images of parts of the arrays containing the letters "A" (b) and "u" (c) respectively. Scale bar, 300 nm. (d) Schematic illustration of the plasma-assisted LbL assembly process and SEM image of the first monolayer of Au nanoparticles after plasma treatment. (e) Optical reflection from AgNP (6 nm in diameter) films with thicknesses of 1, 3, 5, 7, 9, 11, 13, and 15 ML in sequence. (a-c) Reprinted with permission from Ref. 202.
