Graphene, a monolayer of carbon atoms packed into a two-dimensional crystal structure, attracted intense attention owing to its unique structure and optical, electronic properties. In this study, graphite oxide (GO) was prepared using flake graphite by an improved Hummers method. Hydrazine hydrate ...
This chapter is a review of the application of Raman spectroscopy in characterizing the properties of graphene, both exfoliated and synthesized, and graphene-based materials such as graphene-oxide. Graphene is a 2-dimensional honeycomb lattice of sp2-bonded carbon atoms and has received enormous inter...

Raman spectroscopy of graphene and graphite: Disorder, electron–phonon coupling, doping and nonadiabatic effects We review recent work on Raman spectroscopy of graphite and graphene. We focus on the origin of the D and G peaks and the second order of the D peak. The G... AC Ferrari - ...
举例:In order to obtain better confirmation on the presence of H4SiMo12O40, Raman spectroscopic investigation was also conducted, because Raman spectroscopy is a sensitive technique to study supported metal oxide and it is complementary to IR investigation. The Raman spectra of the MoVI@mSiO2 and...
Raman spectroscopy has proven to be a powerful, local structural probe forMnO2.δ-phase MnO2has strong Raman-active(Mn-O)stretching transitions at646 and 575 cm-1.A somewhat weaker transition at510 cm-1is also prominent but less intense inmost δ-phase MnO2 samples.All three of these characte...

3.6 Fourier Transform Raman Spectroscopy. The Raman spectrum for calcined H1 Cr/SiO2 shows no peaks consistent with the presence of chromium oxide or other extra framework chromium species indicating that the chromium may be attached to the silicate walls. Raman spectroscopy is a very useful techniqu...
Few-layer graphene was transferred directly on top of Ag nanoparticles, and the coupling between graphene and localized surface plasmons (LSPs) of Ag nanoparticles was investigated. We found that the surface enhanced Raman spectroscopy of graphene was increased approximately 7-fold by near-fields of ...
Surface-enhanced Raman spectroscopy (SERS) is a highly sensitive technique that enhances the Raman scattering of molecules supported by some nanostructured materials. SERS allows for the structural fingerprinting of low-concentration analytes through the plasmon-mediated amplification of electrical fields or ...
