[×ÊÔ´] Upconversion and Downconversion Fluorescent Graphene Quantum Dots:

A facile ultrasonic route for the fabrication of graphene quantum dots (GQDs) with
upconvertedemissionispresented.Theas-prepared GQDs exhibit an excitation-independent downcon-version and upconversion photoluminescent (PL)
behavior, and the complex photocatalysts (rutileTiO2/GQD and anatase TiO2/GQD systems) were designedtoharnessthevisiblespectrumofsunlight. It is interesting that the photocatalytic rate of the rutile TiO2/GQD complex system is ca.9times larger than that of the anatase TiO2/GQD complex under visible light (¦Ë > 420 nm) irradiation in the degradation of methylene blue.
