Raman and Nanotechnology

The characterization of carbon nanotubes and graphene can be rapidly done using Raman spectroscopy, which has the ability to distinguish between the various structures of the single-walled nanotubes. The number of layers in a nanomaterial can also be determined by the use of Raman spectroscopy, as can the order of the materials. Analysis of nanomaterials for purity and quality can also be achieved by Raman spectroscopy.

Application Notes

Carbon black is a form of amorphous carbon. It is mainly used as reinforcement filler in automobile tires and other rubber products, but is also used in pigments, paint, and carbon paper. Raman spectroscopy is a very effective analytical technology to characterize carbon materials. The fast characterization of carbon black material using Raman spectroscopy is discussed here to demonstrate that Raman technology is well suited for carbon black material characterization.
