摘要

拉曼光谱是一种强大的方法,可以深入了解纳米材料的原子结构和组成,但也可以得出关于其电子性质的结论。它基于光的非弹性散射,能够激发材料中的声子。在半导体纳米晶体领域,拉曼光谱已被用于对晶格畸变、界面、相混合和缺陷形成的分析做出重大贡献。然而,对于材料的电子和晶体结构如何与入射光相互作用以产生观察到的光谱,目前还没有明确的共识。这篇综述简要概述了该方法。然后,它回顾了最重要的发现、当前的发展,并讨论了制定一致模型的努力,该模型允许将该方法作为结构分析的工具。

Raman spectroscopy of colloidal semiconductor nanocrystals
Raman spectroscopy is a powerful method that gives insight into the atomic structure and composition of nanomaterials, but also allows to draw conclusions about their electronic properties. It is based on the inelastic scattering of light, which is able to excite phonons in the material. In the field of semiconductor nanocrystals, Raman spectroscopy has been employed to make significant contributions to the analysis of lattice distortion, interfaces, phase mixing, and defect formation. Yet, there is no clear consensus on how the electronic and crystal structure of the material interacts with the incident light to yield the observed spectra. This review gives a brief overview over the method. It then reviews the most important findings, current developments, and discusses the efforts to formulate a consistent model that allows to establish the method as a tool for structural analysis.
