2011年12月15日 · Raman analysis of rGO shows the restoration of graphitic domains in GO after reduction. The photoluminescence of rGO showed emission in the UV region which is blue shifted along with luminescent quenching as compared to GO.

2017年9月26日 · Raman spectroscopy is a well-known tool to assess molecular structures of carbon materials (graphite, GO, rGO, G and CNT), which can be determined through their Raman spectra.

In this study, in situ electrochemical Raman spectroscopy was applied to clarify the charge storage mechanism in three types of anodes, synthetic graphite, reduced graphene oxide (rGO), and nitrogen-doped reduced graphene oxide (N-rGO). The Li + intercalation phenomenon was measured in LiPF 6 electrolyte solution using a modified coin cell setup.
