One of the most important applications of graphene is in the enhancement of Raman spectroscopy, which has recently attracted the attention of scientists. This article investigates its potential as a substrate for Raman enhancement called graphene-enhanced Raman spectroscopy (GERS). We use rhodamine 6G (R6G) and crystal violet (CV) to illustrate the effect of graphene oxide on Raman enhancement. It was shown that Raman peaks of rhodamine 6G and crystal violet solutions deposited by solution soaking on the graphene-based substrate have significantly increased compared to those deposited on the bare glass substrate. Using a Raman spectrometer, The Raman spectra of these materials were taken and their graphs were compared. It is shown that this method can enhance the Raman signals of molecules of rhodamine 6G and crystal violet.</span></span> Crystal violet, Graphene, Graphene-enhanced Raman spectroscopy, Rhodamine 6G 3 10 http://ijop.ir/browse.php?a_code=A-10-966-1&slc_lang=en&sid=1 Maryam Bahreini m_bahreini@iust.ac.ir 10031947532846005171 10031947532846005171 Yes School of Physics, Iran University of Science and Technology, Tehran, Iran Zahra Sabzevari sabzevarizahra78@gmail.com 10031947532846005172 10031947532846005172 No School of Physics, Iran University of Science and Technology, Tehran, Iran
