表面增强喇曼光谱及其分析应用

Surface-Enhanced Raman Spectroscopy and Its Analytical Application

吸附在粗糙化金属表面的化合物能产生表面增强喇曼散射(简称SERS)效应,其增强因子达10~3～10~7。利用此效应,SERS光谱法已成为一种新的光谱分析方法。近来光导纤维技术也被用于SERS光谱法进行远距离分析。本文将简单介绍SERS增强机理、SERS光谱法的分析应用、各种SERS活性基质、液相色谱的表面增强喇曼光谱检测器以及现场分析的SERS光谱-光导纤维系统。

This paper will give an introduction to surface-enhanced Raman scattering (SERS) enhancement mechanisms, recent developments of this method for analytical applications, various kinds of SERS-active substrates, surface-enhanced Raman spectroscopy detector for liquid chromatography and SERS-fiber optic system for analysis in situ.
