摘要：利用具有准周期结构的硅纳米孔柱阵列（silicon nanoprous pillar array，Si-NPA）为衬底使用浸渍法制备优化Au／Si-NPA活性基底。并利用最优化制备的Au／Si—NPA活性基底对罗丹明6G（Rhoda-mine 6G，R6G）进行探测，研究其表面增强拉曼散射（surface enhanced Raman scattering，SERS）光谱并对其增强原理进行解释。
A quasi-periodic structure of Au/Si-NPA active substrate was fabricated by immersion plating gold on Si-NPA. The optimum Au/Si-NPA active substrate was characterized by FE-SEM and XRD, its SERS enhancement was tested with probe molecule R6G, and the relevant enhance mechanism was analyzed.
