We investigate in this paper the influence of the localized plasmon resonance of gold nano-island structure on the photoluminescence of the exciplex in the polymer blends. The experimental results show that when the particle plasmon resonance overlaps the photoluminescence spectrum of the exciplex,the corresponding emission intensity is enhanced significantly. Furthermore, alonger lifetime is observed with the exciplex emission. We propose that the localized electrical field induced by the particle plasmon resonance increaseds the exciton diffusion length and thus conduces to the formation of the exciplex in the phase separation interface.
