Abstract: The surface structure of organically capped PbS nanocrystals using synchrotron radiation excited core-level photoelectron spectroscopy is studied. The results indicate that the trioctylphosphine ligands passivate only the surface S sites while oleic acid ligands appear to bind mainly to Pb sites.
