ABSTRACT

Characterization of graphene is an important part of graphene exploration which comprises different microscopic and spectroscopic methods. In characterization, the main motive is to determine the number of layers and the purity of sample by evaluating the absence or presence of defects. This chapter discusses some of the spectroscopic aspects. UV-visible spectroscopy is a robust characterization technique that can be used for the structure elucidation of organic molecules and also for both qualitative and quantitative analyses. It is also useful for the characterization of graphite and its derivatives. Raman spectroscopy is used to understand the structural hybridization changes in graphite and its derivatives. The synthesis and characterization of graphitic structures are very important because of the exceptionally high demand in various fields such as electronic devices, energy technology, water purification, dielectric materials, photo catalysis, solar cells, biomedical field, and tyre engineering.
