2023年6月1日 · Raman spectroscopy has now become accepted to be one of the most powerful techniques for characterising structure–property relations in carbon materials, including 0D fullerenes, 1D CNTs and CFs, 2D graphene and its derivatives, 3D graphite and diamond.

2010年1月19日 · Raman spectroscopy is here shown to provide a powerful tool to differentiate between two different sp 2 carbon nanostructures (carbon nanotubes and graphene) which have many properties in common and others that differ. Emphasis is given to the richness of both carbon nanostructures as prototype examples of nanostructured materials.

3 天之前 · Abstract Today, Raman spectroscopy is the main tool for investigating carbon-based materials. In the present work, the results of Raman spectroscopy are generalized for the basic classes of carbon-based materials that differ in the degree of hybridization of the electron orbitals in the carbon atoms. As a result, Raman spectra are obtained for the following carbon-based materials: diamond ...
