摘要
本综述对埃分辨针尖增强拉曼光谱成像技术的最新进展做了一个概述.首先在理论层面介绍了如何理解原子尺度下对光进行限域,并解释了单个分子在这样一个原子级束缚的局域光“照射”下拉曼散射过程是如何发生的.然后,概述了埃分辨针尖增强拉曼光谱技术相关研究领域的发展历程及其最新进展,特别介绍了最近发展的一种新的实空间单分子化学结构可视化重构技术一“扫描拉曼埃分辨显微术”.最后,展望了该技术所具有的这种在单个化学键层面上识别材料化学结构的能力在不同的科学领域的应用前景.
In this review,we present a brief overview on the recent advances in Angstr6m-resolved tip-enhanced Raman spectromicroscopy.We first introduce the theoretical understanding of the confinement of light at the atomistic scale,and explain how the Raman scattering from a single molecule happens under the“illumination”of such an atomically confined light.Then we describe the latest developments on Angstr6m-resolved tipenhanced Raman spectromicroscopy,particularly on a new methodology called“scanning Raman picoscopy”for visually cons true ting the chemical st ruc ture of a single molecule in real space.Finally,we give a perspective of this technique in various applications where iden ti fying the chemical st ruc tu res of mat erials at the chemical bond level is required.
