One-pot facile decoration of CdSe quantum dots on graphenenanosheets: novel graphene-CdSe nanocomposites with tunable fluorescent properties

Abstract

Fluorescent graphene-CdSe quantum dot (QD) (G-CdSe) nanocomposites with tunable optical properties can be prepared by a one-pot facile decoration of CdSe QDs on graphene nanosheets. The formation of such nanocomposites is based on the interaction between the surfactants on the surfaces of the synthesized graphene and the CdSe QDs through electrostatic interactions and van der Waals forces of the long chain alkane surfactants. PXRD, TEM and PL spectra have been acquired to demonstrate the successful decoration of CdSe QDs on graphene nanosheets. This kind of nanocomposite may have potential applications in bio-imaging and light emitting devices in the future.
