Abstract: In this work we demonstrate a facile means to generate fluorescent carbon nanoribbons, nanoparticles, and graphene from graphite electrode using ionic liquid-assisted electrochemical exfoliation. A time-dependence study of products exfoliated from the graphite anode allows the reconstruction of the exfoliation mechanism based on the interplay of anodic oxidation and anion intercalation. We have developed strategies to control the distribution of the exfoliated products. In addition, the fluorescence of these c… Show more

“…This combination of photoluminescent and conductive layers could be used in sandwich light-emitting diodes. Luminescent graphene-based materials can now be routinely produced covering the infrared (IR), visible and blue spectral range [16][17][18][19]27 .…”

“…This results from its electronic structure having an electron affinity as well as ionization potential of around 4.6 eV [1]. In order to tailor the electronic properties of graphite, several groups [2][3][4][5][6] used the technique of so called "intercalation" to introduce additional chemical species in between the layers of graphite as a way to modulate the electronic transport and optical properties.…”

“…The intercalants are consequently classified as donors or acceptors according to whether they donate or extract electrons from the graphitic layers. Examples of electron-donor GICs are KC 8 , CaC 6 , LiC 6 , whereas molecules such as FeCl 3 , and AsF 5 act as electron-acceptors [2]. In both cases, donor/acceptor GICs, the stoichiometric concentration of intercalants with respect to carbon atoms can be varied creating highly ordered macromolecular structures with different number of graphene layers in between intercalant ones (see Fig.…”
