Raman spectroscopy is probably the most important analytical tool available for investigating the many different structures produced from carbon.
You can use Raman to identify all the forms, including graphene, carbon nanotubes (CNT), graphite, diamond, and diamond-like carbon (DLC).
The massive range of consumer products that use carbon-based materials—and the promise of carbon materials for future technologies—make this a key application area for Raman spectroscopy.
