Spectrochim Acta A Mol Biomol Spectrosc. 2014 Dec 10:133:411-6. doi: 10.1016/j.saa.2014.06.054. Epub 2014 Jun 16.

Abstract

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.

Keywords: Ag nanowires; Crystal violet; Surface-Enhanced Raman Scattering; Thiram.
