摘要
近年来,作为一项无损的指纹识别技术,拉曼光谱在细颗粒物分析领域表现出巨大的应用潜力.本文对拉曼光谱在细颗粒物定性分析、定量分析、图像化表征、混合态分析、源解析、pH分析和非均相反应七个方面的研究进展进行了综述.对于传统拉曼光谱存在信号强度不高的问题,通过表面增强拉曼散射(SERS)、尖端增强拉曼散射(TERS)和受激拉曼散射(SRS)技术得到了改进.最后对今后拉曼光谱在细颗粒物分析领域可能的研究方向进行了展望.
In recent years,as a nondestructive fingerprint recognition technology,Raman spectroscopy has shown great application potential in the field of fine-particle analysis.This article reviewed research process in seven aspects:qualitative analysis,quantitative analysis,image characterization,mixing-state analysis,source apportionment,pH analysis,and heterogeneous reaction.The problem of low signal strength of traditional Raman has been improved through technical improvements,such as surface-enhanced Raman scattering(SERS),tip-enhanced Raman scattering(TERS)and stimulated Raman scattering(SRS).Finally,this article prospected the possible research directions of Raman spectroscopy in the field of fine-particle analysis in the future.
