Shell-Thickness Dependence of Hot Electron Transfer in CdSe/ZnS Quantum Dots and Fullerene Derivative Hybrid Systems

The utilization of hot electrons surpasses the Shockley-Queisser limit, and fundamental understanding of hot electrons provides design principles for photo-energy conversion materials. Although the effect of donor-acceptor distance on electron transfer from the lowest excitonic state in quantum dots (QDs) to the acceptor has been studied (cold electron transfer), that of hot electron transfer still remains unclear. In this study, we hybridized CdSe/ZnS QDs with different shell thicknesses and a
