摘要：
Silver nanowires with uniform diameters have been synthesized via the rapid sulfide mediated polyol method. The morphology, structure, and properties of as-prepared samples are characterized by UV-Visible spectroscopy, field emission scanning electron microscopy (FESEM) and X-ray diffraction (XRD), respectively. The mechanism of as-prepared Ag nanowires is provided and discussed. Moreover, as-prepared Ag nanowires are used as a Surface-Enhanced Raman Scattering (SERS) substrate to detect thiram pesticide. The results show that this substrate based on Ag nanowires exhibits high sensitivity and reproducibility for the thiram detection. (C) 2014 Elsevier B.V. All rights reserved.
