【摘要】 主要报道了Raman光谱在单壁碳纳米管研究中的应用。研究了超长单壁碳纳米管平行阵列的可控生长,并利用Raman光谱对纳米管的手性进行了表征。理论和实验研究均表明,在张力作用存在下碳纳米管Raman光谱出现超强呼吸模吸收谱带。利用显微Raman光谱跟踪研究了单壁碳纳米管的定位化学修饰过程。更多还原

【Abstract】 The application of Raman spectra in the study of single-walled carbon nanotubes (SWCNTs) was reported.The con- trolled growth of ultralong SWCNT arrays and the Raman characterization of chirality were studied.Experimental and theoretical studies all show that the abnormal Raman intensity of SWCNTs will appear when the tubes were under uniaxial strain.The mi- cro-Raman has also shown to be a powerful method to characterize the site-specific modification of individual SWCNT.更多还原
