Abstract

Abstract : Graphene nanoflake and CdSe/ZnS quantum dot nanohybrids were assembled in aqueous solution and investigated as potential light harvesting assemblies. Abstract : Graphene nanoflakes and CdSe/ZnS quantum dots were covalently linked in environmentally friendly aqueous solution. Raman spectroscopy and photoluminescence studies, both in solution and on surfaces at the single nanohybrid level, showed evidence of charge transfer between the two nanostructures. The nanohybrids were further incorporated into solar cell devices, demonstrating their potential as light harvesting assemblies.
