| 摘 要： | 采用水热还原法制备得到了立方纳米银晶粒，并用两种不同方法将其制备成基底，两种基底的形貌存在很大差异，一种基底上纳米粒子产生聚集，其聚集体呈单分散分布，另外一种为连续膜。以玫瑰精（RhB）为探针分子测定了基底的SERS效应，发现前者有更好的增强效果，并且对增强机制进行了解释。

| 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. |
