摘要
用YAG脉冲激光器烧蚀去离子水中的Ag片,得到高分散均匀的Ag纳米胶体,通测试发现此Ag胶体系是一种非常高效的SERS活性增强基底。
We ablected Ag plate by Nd: YAG pulse laser in redistilled water. Pure Ag colloids were obtained. The Ag nanoparticles have homogeneous size distributions and have good stability in the colloids. The Ag colloids system were highly efficient SERS-active substrate.
