Abstract
Up to fifty fold increases in water soluble conjugated phenylenevinylene polymer fluorescence are observed when these polymers are adsorbed onto silver nanoparticle treated surfaces with layer-by-layer deposited polyelectrolyte spacers. The silver particle density and spacer thickness dependence of the enhancement are investigated. Using absorption, fluorescence, fluorescence excitation and transient photoluminescence measurments, we infer the relative importance of absorption and emissive rate increases in explaining the observed enhancement. Large blue shifts due to interactions of the molecular excited states with the silver particle plasmons are observed.
