Critchley, Liam. Stolichnov, Igor This is most relevant to single-layer graphene, as more than one layer can significantly alter the absorption properties and ability to tune the absorbance. E-mail: Meanwhile, it indicates that the coexistence of B atoms and oxidized B bonding configurations can help charge transfer in the absorption process.

According to the excited state analysis, BC3 plays an important role in determining the electronic transition, while the effects of BC2O and BCO2 on tuning the electronic and optical properties of GQDs are dictated by their hybridization form of carbon. If you are not the author of this article and you wish to reproduce material from to access the full features of the site or access our. Zhang, Gang 2018. Do you have a review, update or anything you would like to add to this article? Ionescu, Adrian M. It such be noted that this article centers around non-functionalized graphene (i.e. Memisevic, Elvedin . These quantumly confined regions then open the bandgap, which enables conventional photoluminescence mechanisms to occur. In this case, the mechanism of light emittance is due to high temperature of the femtosecond laser photons which hit the graphene sheet, as they are known to emit in the visible light spectrum.

It is a process often used in electronics to modulate the current, as a change in the Fermi level changes the conductivity, as well as for tuning the transmission of an optical source.
