样品未作任何特殊处理，用显微共焦拉曼光谱仪对样品不同部位进行分析。
The different positions of the samples are analytically detected with confocal Raman Spectroscopy.
以共焦显微系统为平台，研究了不同浓度的R6G银溶胶的表面增强共振拉曼散射（SERRS）光谱， 结果表明不同浓度溶液中的R6G分子表现出了不同的光谱特性。
R6G was incubated in three kinds of silver colloid with different low concentrations, and its surface-enhanced resonance Raman scattering (SERRS) was studied with a confocal microscopy system.
