(Received 7 May, 2010 : revised 26 August, 2010 : accepted 14 September, 2010)
We studied the dependence of the photoluminescence (PL) intensity of poly (3-methylthiophene) (P3MT)-Au hybrid nanowires on the polarization direction of the input illumination. We used a high-resolution laser confocal microscope and obtained and quantitatively analyzed the PL images of P3MT-Au nanowires for various input illumination polarizations. We found that about 30 ∼ 40%
relative increase in the PL intensity when the polarization of the input illumination was parallel to the nanowires over as compared to when it was perpendicular to the nanowire. This result was similarly observed for P3MT nanowires without a Au nanowall, indicating that the input polarization dependence of PL intensity of P3MT nanowires has no correlation with the presence of the Au nanowall.
