    摘要:

    采用水熱還原法制備得到了立方納米銀晶粒，并用兩種不同方法將其制備成基底，兩種基底的形貌存在很大差異，一種基底上納米粒子產(chǎn)生聚集，其聚集體呈單分散分布，另外一種為連續(xù)膜。以玫瑰精（RhB）為探針分子測(cè)定了基底的SERS效應(yīng)，發(fā)現(xiàn)前者有更好的增強(qiáng)效果，并且對(duì)增強(qiáng)機(jī)制進(jìn)行了解釋。

    Abstract:

    Silver nanocubes synthesized by hydrothermal-Induced method were prepared into substrates using two different methods. The morphologies of these two substrates were different from each other. On one substrate, the nanoparticles congregated into congeries which were monodisperse, but another was a continuous film. SERS activities of silver substrates were detected by using RhB as probe molecule The results showed that the former has better SERS activity. The mechanism of SERS effect was also discussed.
