Paper Abstract

We investigate the influence of particle plasmon resonance of Au nanoislands structures on the exciplex emission in the polymer blend of poly (9, 9'-dioctylfluorene-co-benzothiadiazole) (F8BT) and poly (9,9'-dioctylfluorene-co-bis-N,N'- (4-butylphenyl)-bis-N,N'-phenyl-l,4-phenylenediamine) (PFB). The experimental results indicate that when the particle plasmon resonance of the gold nanoisland structures overlaps the spectral range of the exciplex emission, significant enhancement of the photoluminescence can be observed. Furthermore, longer lifetime has been measured for the red-shift emission of the exciplex. We proposed that the localized field due to the particle plasmon resonance of the Au nanoislands has modulated the mechanisms for the formation of exciplex, which may be related to the exciton diffusion, charge transfer, and phase separation at the interface between the two materials.
