Transmission through Ag/Organic Multilayers Using Continuous and Island Metal Films

We present the results of transmission spectrum measurements of Ag/tetraphenyldiphenyldiamine periodic multilayers, as well as Ag/SiO₂ in the visible and near IR spectral range. Using continuous silver films, these one-dimensional multilayers transmit visible light in controllable bands and stop IR light. Using island metal films, surface plasmon modes are excited, which exhibits broad absorption features covering the entire visible spectral range. This work successfully extends the discussion of metal-dielectric one-dimensional photonic crystals to metal-organic cases and exhibits the linear optical properties of surface plasmon modes at the island metal/organic interface.
