title: Syntheis and Photocurrent Performance of Graphene Oxide-CdTe/CdS Nanocomposite.
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 graphene oxide significantly decreased its photoluminescence, which indicated effective transfer of photo-excited electrons from CdTe/CdS to graphene oxide. The generation of photocurrent on illumination of the GO-CdTe/CdS nanocomposite was studied. Significant enhancement in photocurrent induced by GO in CdTe/CdS QDs film had also been demonstrated due to increasing the charge separation and electron conduction.
