Abstract

Picosecond time-resolved spectroscopy studies are performed on surface plasmon (SP) mediated conjugated polymers. Huang-Rhys factor and photoluminescence (PL) decay time at low temperature were unchanged with the respect to thickness of Ag nanostructures due to a decrease in the surface plasmon coupling rates (Okamoto , Appl. Phys. Lett., vol. 87, 07112, 2005). However, Huang-Rhys factor and PL decay time at room temperature were increased with respect to the thickness of the Ag nanostructures. Relatively strong emission from the interchain excitons of surface plasmon (SP) mediated conjugated polymers in the film-like Ag nanostructure was verified by PL decay dynamics from time-resolved photoluminescence (TR-PL) measurement.
