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.
通过快速硫化物介导的多元醇法合成了具有均匀直径的银纳米线。分别采用紫外可见光谱、场发射扫描电子显微镜（FESEM）和X射线衍射（XRD）对所制备样品的形貌、结构和性能进行了表征。提供并讨论了所制备银纳米线的形成机理。此外，将所制备的银纳米线用作表面增强拉曼散射（SERS）基底来检测福美双农药。结果表明，这种基于银纳米线的基底对福美双检测具有高灵敏度和重现性。
