摘要
通过改进电极修饰方法,在粗糙银电极上沉积银纳米颗粒,得到了哌啶分子吸附在覆银银电极上的高质量SERS谱,并研究了电位对哌啶分子在这种覆银银电极上SERS光谱的影响。实验表明,沉积有银纳米颗粒的粗糙银电极是一种新的高效SERS活性基底,分析并解释了覆银银电极能产生极强的增强效应的可能原因。
Roughened silver electrode modified with silver nanoparticles was used as a substrate, on which high- quality SERS spectra of piperidine were obtained, and the potential- dependent SERS spectra of piperidine adsorbed on silver - modified silver electrode were stud- ied. The results indicate that the silver- modified silver electrode was a highly SERS- active substrate. And the probable reasons of the giant Surface Enhanced Raman Scattering effect are given.
