基于“热点”效应的表面增强拉曼散射光谱研究
Surface-Enhanced Raman Spectrum based on the “Hot-Spots” Effect
摘要
本文利用罗丹明6G在银胶体粒子聚集点上的表面增强拉曼光谱的强度变化, 采用逐点扫描获得拉曼光谱的“Mapping”方法, 获得了不同的银胶体粒子聚集点对吸附的R6G表面增强拉曼光谱强度的影响。分析了 “热点”对拉曼散射的增强的作用, 表明“热点”的增强强度和纳米粒子的聚集程度有关。
Abstract
Surface-enhanced Raman Spectrum (SERS) of R6G obtained by Mapping is studied in this paper. The different nanoparticle clusters have an affect on the intensity of SERS. The function of “Hot-Spots” to SERS is analyzed. The result showed that the enhanced intensity of “Hot-spots” is based on the number of nanoparticles in a cluster and the distance of nanoparticles.
