Ligand adsorption energy and the postpurification surface chemistry of colloidal metal chalcogenide nanocrystals Ghent University
The binding of ligands to nanometer-sized surfaces is a central aspect of colloidal nanocrystal (NC) research, for which CdSe NCs were mostly used as the model system to evaluate different surface chemistries. Here, we take the opposite approach and analyze the binding of a single ligand to two different materials. Using CdSe and CdS NCs of similar size and shape and purified with the same protocol, we show that both NCs are capped with tightly ...
