【求助】請大家科普一下拉曼光譜的D-band,G-band,RBM 已有8人參與
|

在graphene,graphite,carbon nanotube中,請問這幾個帶,是如何在拉曼光譜上確定的?尤其是,這個RBM(徑向呼吸模式) 有什么特殊的地方嗎? [ Last edited by vasp001 on 2010-7-8 at 21:59 ] |

可以讀讀下面的3篇文獻: Phys. Chem. Chem. Phys., 2007, 9, 1276 - 1290, DOI: 10.1039/b613962k Studying disorder in graphite-based systems by Raman spectroscopy M. A. Pimenta, G. Dresselhaus, M. S. Dresselhaus, L. G. Cançado, A. Jorio and R. Saito http://www.rsc.org/Publishing/Jo ... le.asp?doi=b613962k J. Chem. Phys. 53, 1126 (1970); doi:10.1063/1.1674108 (5 pages) Raman Spectrum of Graphite F. Tuinstra and J. L.

C 2008, 112, 10637–10640的Introduction拷貝出來的。 Raman spectroscopy has historically been used to probe structural and electronic characteristics of graphite materials, providing useful information on the defects (D-band), in-plane vibration of sp2 carbon atoms (G-band), as well as the stacking orders (2D-band).5 The G-band of graphite materials is a doubly degenerate (TO and LO) phonon mode (E2g symmetry) at the Brillouin zone center,6 whereas the D-band is due to phonon branches around the K point and requires a defect for its activation.5 The evolution of the 2D-band for different graphene sheets has been used for determining graphene thickness as well as for probing electronic structures through the double resonance process.7,8 The symmetric and sharp 2D-band (~30 cm-1) can be used as a detector for monolayer graphene.7,8 |
