本文主要研究银纳米结构的制备及其表面增强拉曼散射效应。采用电镀技术在硅片上制备了银纳米线和纳米颗粒。通过X射线衍射、扫描电子显微镜、透射电子显微镜和X射线能量色散谱仪以及选区电子衍射对样品进行了表征，结果表明银纳米结构的形成依赖于过电位。所制备的银纳米线具有面心立方结构，沿面心立方方向生长.并对生长机理作了进一步的探讨。表面增强的拉曼散射效应与所产生的银纳米结构实现。
This very paper is focusing on the preparation of silver nanostructures and the surface enhanced Raman scattering effect of the silver nanostructures produced. Via electroplating technology, silver nanowires and nanoparticles were prepared on silicon wafers. Characterization was performed by X-ray diffraction, scanning electron microscope, transmission electron microscope equipped with X-ray energy dispersion spectroscope and selected area electron diffraction, which reveals that the formation of silver nanostructures depends on the over-potential. The produced silver nanowires are of crystalline FCC structure and grow in 〈011〉 direction. The growth mechanism has been further discussed. The surface enhanced Raman scattering effect is achieved with the silver nanostructures produced.
