abstract

  • Graphene quantum dots (GQDs), sheets of graphene with less than 10 layers and lateral dimensions smaller than 100 nm, possess strong quantum confinement and edge effects. 1, 2 Thus, they possess unique physical properties such as strong wavelength-dependent down-and up-conversion photoluminescence (PL), 3− 7 which can be tailored for specific applications by controlling their size, 8 shape, defects, and functionality. 9 In contrast to classic PL nanoparticles, such as metal or silicon quantum dots, GQDs are biocompatible, 10, 11 photostable, 12, 13 and inherit superior thermal, electrical, and mechanical properties from the graphene. 14 However, although these features can greatly contribute to various state-of-the-art applications (eg, flexible photovoltaics, 15 flash memory devices, 16 bioimaging, 17 antibacterial systems, 18 artificial peroxidase, 19 light-emitting diodes, 20 …
