A homogeneous array of light-emitting rubrene nanowires is fabricated through an organic vapor transport method by using an Al2O3 nanoporous template. The light emissions of an isolated single strand of rubrene nanowires are observed through nanometer-scale laser confocal microscope (LCM) photoluminescence (PL), and color charge-coupled device experiments. The line-width of LCM PL spectra for the single rubrene nanowire was much broader than that for rubrene single crystals, originating from the light emission of mixed polarized bands due to different crystal growth characteristics.
