[交流] MWCNT在260~290nm波长范围内的吸收峰

  很多文献用分光光度(UV-vis photospectrometer)表征MWCNT在溶液中悬浮的“浓度”。SWCNT在260~290nm波长范围内有吸收峰,这是有理论解释的,吸收峰和SWCNT直径、手性有关(H.J. Huang, H. Kajiura, and R. Maruyama, et al. , Relative optical absorption of metallic and semiconducting single-walled carbon nanotubes. JOURNAL OF PHYSICAL CHEMISTRY B, 2006. 110(10): p. 4686-4690.)。可是,看了N多文献,看了N多二次文献,却从来没有看到一篇文献正面解释为什么MWCNT有这个吸收峰。所有文章几乎都套用SWCNT的理论解释,来说明MWCNT用UV-vis的道理。真不解。两者的机理一样吗?
