Figure 4From: Enhanced plasmonic behavior of bimetallic (Ag-Au) multilayered spheres Simulated extinction efficiency for Au-Au and Ag-Au DCN structures. Simulated extinction efficiency as a function of the wavelength for (a) Au-Au and (b) Ag-Au DCN structures, having t 0 = t 2 = 5 nm, while t 1 and t 3 are varied simultaneously (t 1 = 2, ..., 14 nm; t 3 = 16 nm - t 1 ).Back to article page
