How Does Spectroscopy Aid in the Characterization of Nanomaterials?
Spectroscopy provides a wealth of information that is essential for the characterization of nanomaterials. For example, Raman spectroscopy can identify the presence of defects in a graphene sheet, while UV-Vis spectroscopy can determine the size and distribution of nanoparticles in a solution. FTIR spectroscopy can reveal the chemical modifications on the surface of nanomaterials, and XPS can provide insights into the oxidation states of metal nanoparticles.
