Graphene quantum dots: Emerging organic materials with remarkable and tunable luminescence features
[摘要] Graphene quantum dots (GQDs) are recently discovered carbon-based materials that correspond to nanofragments of functional graphene-like structures. They could be synthesized either by conventional stepwise organic synthesis or, more rapidly, by either top-down or bottom-up one step approaches. Regardless of the synthetic route, GQDs display photoluminescence features (fluorescence and/or phosphorescence) that could be finely tuned according to their surface and edges chemistry. This makes this new organic material highly valuable in applications ranging from imaging, sensing and optoelectronics. (C) 2020 Elsevier Ltd. All rights reserved.
