Abstract

The scientific community has given much interest to graphene in recent years because of its good mechanical, thermal and electrical properties. Nonetheless, applications in optics and optoelectronics can be limited due to the absence of a bandgap. In order to engineer a bandgap, we can reduce the size of graphene into graphene quantum dots (GQDs). GQDs synthesis is primarily described via top-down methods (lithography, hydrothermal and electrochemical approaches). Though effective, these methods do not allow accurate control of the size, shape and edges of the GQDs. On the other hand, bottom-up graphene materials have developed exponentially for the last decade with the synthesis of highly controlled graphene nanoribbon structures and moderately soluble graphene quantum dots. Our group demonstrated that bottom-up GQDs could act as singlephoton emitters exhibiting high brightness and stability
