| 摘 要： | 基于扩散限制聚集过程机制合成的大型银分形网络被用作表面增强拉曼散射活性衬底材料.此衬底材料具有很好的拉曼增强特性以及很宽的动态响应范围.其较大的增强因子可归结为高度局域化的等离激元共振.

| Abstract: | A convenient nanotechnique to obtain large silver fractal networks based on diffusion-limited aggregation process is demonstrated for a surface-enhanced Raman scattering(SERS) active substrate.The silver fractal networks are of high SERS enhancement factor,large dynamical range.The observed SERS efficiency can be explained in terms of strongly localized plasmon modes relative to the single particle plasmon resonance. |

| Keywords: | fractai surface-enhanced Raman scattering plasmon resonance |
