Raman spectra of carbon nanowalls (CNWs) grown using dc plasma-enhanced chemical vapor deposition were analyzed. The Raman spectra of CNWs exhibitedGandDbands at1580and1350cm1, respectively. It is found that the bandwidth of theGband is relatively narrow, even when the peak intensity ratio ofD...
nanotubes are summarized, followed by a reviewof the novel experimental findings for each of the features in the first order and second order Raman spectra for single wall carbon nanotubes. These results are presented and discussed in connection with theoretical considerations. Raman spectra for...

The Raman spectra of the various allotropes of carbon are best understood in the framework of solid-state physics. Diamond has the same structure as silicon and germanium, with two atoms in the unit cell. All C–C bonds are tetrahedral (sp3 ) and the lattice is cubic, so there is one...
Temperature dependence of the Raman spectra of carbon nanotubes We report on a temperature dependence of the frequency of all the major peaks in the Raman spectra of carbon nanotubes, using different excitation laser po... F Huang,KT Yue - 《Chinese Journal of Light Scattering》 被引量: 204...

X-ray Raman spectra of the carbon K-edge have been recorded using 6.461 keV radiation for a petroleum asphaltene. By comparison with coronene, graphite, and paraffin standards, the asphaltene spectrum is seen to be composed of contributions from saturated and aromatic carbon species. The information...
The result of the research is synthesized multiwall nanotubes (MWNT), the identification of which is confirmed by the study of Raman spectra of the obtained samples. The search for new methods of creating catalytic systems (catalyst/carrier), which allow controlling the structure of carbon ...
