Graphene – CdSe/ZnS quantum dots conjugated systems: charge transfer phenomena and their applications

Zero-dimensional colloidal semiconductor nanocrystals, known as quantum dots (QDs), attract immense attention in the field of photonics due to their size-dependent tunable optoelectronic properties. Their interaction with conductive surfaces is often reported to provide energy transfer instead of the charge transfer mechanism under presence of optical excitation. In this work, we demonstrate the role of single layer graphene (SLG) as an efficient charge transfer agent when conjugated with CdSe/ZnS core/shell quantum dots.
