Abstrakt: Spectral and structural properties of two-layered polyparaphenylene-silver nanostructures fabricated by a successive thermal evaporation of appropriate materials in vacuum have been studied. We have established an unusual large long-wave shift of the metal nanoparticle surface plasmon absorption resonance (SPAR) and analyzed the main mechanisms of the shift observed. Together with the Coulomb dynamic screening of collective electron oscillations in a metal nanoparticle by the matrix material, we have also considered an additional mechanism caused by the coupling of polyparaphenylene π- electrons with silver valence electrons.
