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？ |
