TLDR
In this paper, a review of recent advances on the use of Raman spectroscopy to study and characterize carbon nanostructures is presented, including Stokes-anti-Stokes correlation, tip-enhanced Raman Spectroscopy in two dimensions, phonon coherence, and high-pressure and shielding effects.Abstract:
This article reviews recent advances on the use of Raman spectroscopy to study and characterize carbon nanostructures. It starts with a brief survey of Raman spectroscopy of graphene and carbon nanotubes, followed by recent developments in the field. Various novel topics, including Stokes–anti-Stokes correlation, tip-enhanced Raman spectroscopy in two dimensions, phonon coherence, and high-pressure and shielding effects, are presented. Some consequences for other fields—quantum optics, near-field electromagnetism, archeology, materials and soil sciences—are discussed. The review ends with a discussion of new perspectives on Raman spectroscopy of carbon nanostructures, including how this technique can contribute to the development of biotechnological applications and nanotoxicology.read more

TL;DR: This work shows that graphene's electronic structure is captured in its Raman spectrum that clearly evolves with the number of layers, and allows unambiguous, high-throughput, nondestructive identification of graphene layers, which is critically lacking in this emerging research area.

Raman Spectrum of Graphite
F. Tuinstra,J. L. Koenig +1 more
TL;DR: Raman spectra are reported from single crystals of graphite and other graphite materials as mentioned in this paper, and the Raman intensity of this band is inversely proportional to the crystallite size and is caused by a breakdown of the k-selection rule.

Raman spectroscopy in graphene
TL;DR: In this article, the authors discuss the first-order and double resonance Raman scattering mechanisms in graphene, which give rise to the most prominent Raman features and give special emphasis to the possibility of using Raman spectroscopy to distinguish a monolayer from few-layer graphene stacked in the Bernal configuration.
