T1 - Recent Advancements of Novel core-shell CdSe Nanocrystals and their Characterization with Single Particle Spectroscopy N2 - Here, we report on the recent advancements in the synthesis and optical properties of novel core-shell CdSe semiconductor nanocrystals (SCNC) with either a thick monolithic shell of CdS or thin multi-shells of succeeding CdS and ZnS monolayers, characterized by steady state and time-resolved fluorescence spectroscopy at the ensemble level. SCNC samples, chosen upon the size of their photoluminescence quantum yield (PL QY), were subsequently investigated at the single particle level using a custom build confocal laser scanning microscope to obtain information on brightness, blinking behavior, and decay kinetics of single SCNCs and correlate these properties with their surface morphology. The results of this study can help to identify new synthetic routes and surface modifications to colloidally and photochemically stable SCNCs with a PL QY of close to unity.
