I am working on the preparation of graphene using electro-exfoliation of graphite. But I do not have RAMAN, SEM, or TEM. But I do have a spectrofluorometer in the lab I work in. Can this instrument help with the characterization?
Hello Omar A. Abdulrazzaq ,
Spectrofluorometry will give you information about the fluorescence of the materials. Graphene-like materials are non-fluorescent but when oxidized (GO) they can emit a signal at a certain wavelength.
Usually you would, indeed, use other techniques like RAMAN spectroscopy, XPS, XRD...
However it is possible to visualize "the strong fluorescence quenching effect" of graphene based, single atomic layer carbon sheets with a common fluorescence microscope by applying a dye doped polymer coating. According to the last paper attached [Visualizing Graphene Based Sheets by Fluorescence Quenching Microscopy. Jaemyung Kim, Laura J. Cote, Franklin Kim, and Jiaxing Huang*
Department of Materials Science and Engineering, Northwestern University, Evanston, Illinois 60208, USA].
The following papers could also be interesting for your study.
