A study was conducted to synthesize, characterize, and examine optical properties of poly(9,9-dioctylfluorene) (PFO) nanowires, with pronounced β-phase morphology. The study revealed that the enhanced optical and electrical properties of β-phase PFO enable it to be used in a number of applications, such optical switching, organic electroluminescence, and electrically pumped organic lasing. It was found that PFO nanowire mats fabricated for electrochemiluminescence and electroluminescence devices exhibited PFO β-phase emission. The results show that the nanowires acted as self-doped one-dimensional (ID) nanostructures in which the PFO β-phase dominated the luminescence behavior, after optical, electrochemical, and electrical excitation.
