Strongly green-photoluminescent graphene quantum dots for bioimaging applications

Chem Commun (Camb). 2011 Jun 28;47(24):6858-60. doi: 10.1039/c1cc11122a. Epub 2011 May 17.

Abstract

Strongly fluorescent graphene quantum dots (GQDs) have been prepared by one-step solvothermal method with PL quantum yield as high as 11.4%. The GQDs have high stability and can be dissolved in most polar solvents. Because of fine biocompatibility and low toxicity, GQDs are demonstrated to be excellent bioimaging agents.
