Abstract:Graphene with two-dimensional carbon nanostructures provides a potent strategy to enhance optoelectronic performance of semiconductor nanoparticles based light harvesting assemblies. Graphene oxide-CdTe/CdS (GO-CdTe/CdS) nanocomposites were successfully prepared by CdTe/CdS quantum dots (QDs) formed on the surface of graphene oxide sheets. The structure and optical properties of GO-CdTe/CdS nanocomposites were studied in detail. Photoluminescence measurements showed that the integration of CdTe/CdS QDs with gr… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
