文摘 石墨烯是一种只有一个原子层的二维原子晶体,它是构成零维富勒烯、一维碳纳米管和三维石墨等其他碳同素异形体的基本结构单元,具有很多独特的电子及力学性能,因而吸引了化学、材料及其他领域众多科学家的高度关注。拉曼光谱作为一种灵敏便捷的表征方法,在石墨烯的研究中起到重要的作用。该综述总结了近年来拉曼光谱在石墨烯表征中的应用,在对单层石墨烯的典型特征峰作详细介绍的基础上,通过对拉曼谱图中D峰、G峰和2D峰的强度、位置和半峰宽变化情况的分析,可以快速而准确地表征出石墨烯的层数,并可以对石墨烯的堆垛方式、边缘手性和掺杂程度进行判定。同时,也系统地分析了在石墨烯制备与测试过程中基底、掺杂、温度和激光功率等因素对拉曼谱图中D峰、G峰和2D峰的强度、位置和半峰宽的影响。
其他语种文摘 Graphene is a kind of two-dimensional atomic crystal with one atomic layer,which is the basic structure unit of other dimensions of graphite materials,such as zero dimensional fullerenes, one-dimensional carbon nanotubes and three-dimensional graphite.Graphene has a lot of unique electronic and mechanical properties,which have attracted high attention of many scientists in the field of chemistry,materials and other fields.Raman spectroscopy as a sensitive and convenient characterization method,has played a very important role in the study of graphene.Raman spectroscopy is an integral part of graphene research.The application of Raman spectroscopy in graphene characterization in recent years is reviewed in this paper.The characteristic peak of monolayer graphene was first intnduced. Then,through the analysis of the changes of D peak,G peak and 2Dpeak intensity,position and half peak width of Raman spectra,the number of graphene layers can be quickly and accurately characterized,as well as,the stacking orders,edge chirality and doping degree of graphene were defined. At the same time,the effects of substrate,doping,temperature and laser power on the intensity, position and half width of D peak,G peak and 2Dpeak of Raman spectra in the process of preparing graphene were also systematically analyzed.
