Abstract:

9,10-Bis(3,5-difluorostyryl)anthracene (TFDSA) organic nanowires with high quality were fabricated by the reprecipitation method. The nanowires were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and photoluminescence (PL) spectroscopy etc. The results show flat the nanowires are 20—30 μm in length and 400 nm in width, and emits strong green fluorescence with a peak at 538 nm and typical strong waveguide behavior. Asprepared TFDSA nanowire is able to serve as single wire active optical waveguide due to propagating light on a sub-wavelength scale. TFDSA can be used as candidates for potential nanoscale photonic devices.
