Abstract

Vertical organic nanowire arrays of 1,5-diaminoanthraquinone (DAAQ) on solid substrates are prepared by a facile physical vapor transport method. Electron diffraction is used for determining the crystal structure and growth direction of the nanowires, which can be used as optical sensor materials.

Abstract

High-density ordered core−sheath nanopillars of fullerene C60/C70loading with colloidal Au nanoparticles were fabricated with a template method. The anodic aluminum oxide (AAO) template was first imbedded with the fullerene C60/C70molecules and then followed by a pressure-difference approach for Au colloid. High-quality surface-enhanced Raman scattering (SERS) spectra of fullerene C60/C70were obtained. The spectra show intense SERS signals with a fluorescence-free background, even with a 514 nm excitation at which the normal Raman of fullerene C60/C70present poor signal-to-noise. The assembly of the fullerene C60/C70on the inner walls of the AAO pores along the Au nanopillars lead to fluorescence quenching; meanwhile, the high-density and ordered arrays of Au nanopillars contribute to surface plasmon resonance for the SERS effect.
