Energy transfer from semiconducting polymer nanoparticles to metal nanoparticles

Abstract

Here, we report the energy transfer from PVK polymer nanoparticles to gold nanoparticles using steady state and time resolved spectroscopy. There is a pronounced effect on the PL quenching (89%) and shortening of lifetime of PVK polymer nanoparticles during the interaction with the Au nanoparticles. The calculated energy transfer efficiency is 61.4%. A stochastic model for the kinetics of energy transfer from polymer nanoparticles to Au nanoparticles has been proposed. By analyzing the time-resolved fluorescence decay curves of polymer nanoparticles in absence and presence of Au nanoparticles, we calculate the energy transfer rate and correlate with experimental resonance energy transfer data.
