同时测量了碳纳米管（Ｄ－ＣＮＴ）和高取向热解石墨（ＨＯＰＧ）的拉曼光谱，第一次分别在ＨＯＰＧ和Ｄ－ＣＮＴ中观察到了位于４２６５ｃｍ－１和４２４８ｃｍ－１的（Ｇ＋Ｄ＊）三级模的拉曼散射；拉曼谱的研究显示，Ｄ－ＣＮＴ的结构比ＨＯＰＧ的无序，同时也进一步表明此无序程度主要来源于结构的缺陷，而非石墨层卷曲成筒状之故
The Raman spectra of carbon nanotubes (D-CNTs) and highly oriented pyrolytic graphite (HOPG) were measured simultaneously. The first time, the G + D * at 4265cm-1 and 4248cm- ) Raman spectra of Raman spectra show that the structure of D-CNT is more disorder than that of HOPG, and further indicates that the degree of disorder mainly comes from the structural defects, while the non-graphite layer curls into a cylinder So why?
