Light Harvesting in SC Core-Shell Nanocrystals — •Peter Lemmens¹, Hongdan Yan¹, Abhinandan Makhal², and Samir Kumar Pal² — ¹IPKM, TU-BS, Braunschweig — ²SNBC, Kolkata, India

The effect of capping and functionalization of core/shell type CdSe/ZnS semiconductor QDs is investigated by coupling/complexation with benzoquinone and TiO₂ nanoparticles using ps resolved time correlated single photon counting and fs carrier dynamics. Our aim is to improve photostability and understand energy transfer involved in light harvesting. Work supported by DFG.
