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.
