Fabrication of fluorescent nitrogen-rich graphene quantum dots by tin( iv ) catalytic carbonization of ethanolamine

摘要: A novel metal catalytic strategy, arising from the coordinated interaction between ions tin(IV) and ethanolamine, was presented to prepare nitrogen-rich graphene quantum dots (N-rich GQDs) with excellent luminescence properties. In contrast previous GQDs produced by bottom-up route, which usually involves complex harsh synthetic procedures, we obtained N-rich using a single reactant source under mild reaction conditions. Moreover, prepared have shown promising applications as fluorescence probe toward folic acid.
