    Abstract

    The photoluminescence (PL) spectra and images of a single strand of poly(3-hexylthiophene) (P3HT) nanowires with different doping states were compared by means of a laser confocal microscope with a high spatial resolution. The P3HT nanowires were electrochemically synthesized by using an ionic liquid as a dopant. From the ultraviolet and visible absorption spectra, the doping and dedoping effects of the P3HT nanowires through the treatment of organic solvent were investigated. The electrical conductivity of the single strand of the lightly doped P3HT nanowires was estimated to be ∼3.5× 10-3 Scm, which was higher than that (∼5.4× 10-5 Scm) of the dedoped one. From the laser confocal microscope PL experiments, we quantitatively observed more homogeneous and three to eight times brighter light emission from the single strand of the dedoped P3HT nanowires.
