固/液系统中SERS的不同增强效应的研究

Electromagnetic and non-electromagnetic enhancement of SERS for solid/liquid systems

以吡啶水溶液/银镜体系为实验对象,通过对不同吸附分子层下发生在银表面上吡啶分子SERS谱的两个特征峰1004cm^(-1)和1010cm^(-1)的实验观测,对固/液体系中的不同增强效应进行了实验研究,并对吡啶/银镜系统中吡啶分子在银表面上的单层饱和吸附所对应的溶液浓度进行了讨论。

In solid/liquid systems, the enhancement factors of electromagnetic and non-electromagnetic is intensively studied by measuring the characteristic peaks at 1004 cm-1 and 1010 cm-1 appearing in SERS spectra of pyridine on Ag surface. The concentration corresponding to the saturated adsorption of pyridine on Ag surface is also discussed.
