Optical Study of Poly (9,9-Dioctylfluorene) Isolated by AIB₂OB₃ Flat Rafts

Abstract:

Nanocomposite films of poly (9,9-dioctylfluorene) (PFO)/Al₂O₃ have been prepared by blending the conjugated polymer solution with alumina nanoparticle dispersion in common organic solvent and investigated in terms of the optical property. A blue shift of the photoluminescence (PL) spectrum for the as fabricated PFO/Al₂O₃ nanocomposite film was observed as compared to the results obtained from the bulk PFO film, the maximum of the PL emission peaks occurs at 442 nm in the bulk film while after the incorporation of the alumina nanoparticles the maximum appears at 420 nm in the spectrum for PFO/Al₂O₃ nanocomposite film. The dependence of fluorescence blue shift of PFO on the concentration of Al₂O₃ was investigated. The isolation of the conjugated polymer chains by the flat rafts of alumina nanoparticles was shown to play a key role for the obtained blue shift.
