Raman spectra of composite aerogels of polytetrafluoroethylene and graphene oxide (reduced grahpene oxide) (PTFE-GO (RGO)) are obtained and described. Five peaks (two Gaussians and three pseudo-Vogt functions) are used to describe spectra in the region of 800-2100 cm 1. Thermal and hydrazine...
We show the evolution of Raman spectra with a number of graphene layers on different substrates, SiO 2 /Si and conducting indium tin oxide (ITO) plate. The... A Das,B Chakraborty,AK Sood - 《Bulletin of Materials Science》 被引量: 337发表: 2008年 Raman spectroscopy of graphene and bilay...
Raman spectra of epitaxial graphene on SiC and of epitaxial graphene transferred to SiO2 Raman spectra were measured for mono-, bi- and trilayer graphene grown on SiC by solid state graphitization, whereby the number of layers was pre-assigned ... DS Lee,C Riedl,B Krauss,... - 《Nano ...
intensity distributions among the observable modes (e.g., the skeletal breathing frequency of benzene) compared with those observed by infrared spectroscopy and because Raman spectra of species on oxide-supported metals have a much wider metal oxide- transparent wavenumber range than infrared spectra. ...
Raman spectraCrystal defectsDispersionGraphene sheets that are now routinely obtained by the exfoliation/reduction of graphite oxide exhibit Raman spectra unlike traditional graphene systems. The general attributes of the Raman spectra of these 'wrinkled graphene' are first reaffirmed by evaluating the ...
) of our reduced graphene oxide powder sample is in good agreement with the literature, but the position is 3 cm-1 higher than that of the initial graphite (1581 cm-1).This shift was also observed when going from a graphite crystal to a single graphene sheet, in which the G band shift...
Hence, Stokes lines have stronger intensity and are generally measured in Raman spectroscopy3. Owing to the physical mechanism at their basis, Raman spectra are sensitive to any change in the material that alters the energy of optical phonons, like the breaking or formation of chemical bonds, ...
Graphite oxide(GO)was successfully silylated by3-mercaptopropyltrimethoxysilane.The surface-enhanced Raman scattering spectrum of the silylated GO sheets sandwiched between colloidal silver nanoparticles and silver piece is presented.The Raman signal shows a104enhancement compared to that of bulk GO.The large...
The vibrational properties and Raman spectra of graphene nanoribbons with six different edges have been studied by using the first-principles calculations. It is found that edge reconstruction leads to the emergence of localized vibrational modes and new topological defect modes, making the different ...
