Graphene quantum dots from chemistry to applications

Spectroelectrochemistry of Quantum Dots

“…A number of potential applications have been proposed for GQDs . The most attractive characteristic of GQDs with respect to semiconductor QDs is the high availability of carbon.…”

“…Moreover, in principle, GQDs show very low toxicity, therefore high biocompatibility, and they can be solubilized in very different solvents. The possibility of the functionalization of their edges is also very important for a number of applications . However, this new nanomaterial needs to be studied in a deeper way.…”

[8,38] The most attractive characteristic of GQDs with respect to semiconductor QDs is the high availability of carbon.

“…A number of diverse QDs with different composition have been shown in literature. [1][2][3][4][5][6][7][8][9][10][11][12] Most of them are nanocrystals (NCs) with semiconductor properties, but also this terminology has been applied to carbon nanostructures. All the nanostructures included in the term QD have in common the nanometre size of the structure, which usually provides a quantum confinement effect that originates a particular density of electronic states, inducing the energy level separation [2,[13][14][15] and producing an increase of the bandgap (HOMO-LUMO gap, E g ) with decreasing size.…”
