Experimental and Theoretical studies in an hybrid CsSe nanocrystal-organic interface: trap states and role of the ligands

摘要

We time-resolved the excited states dynamics of hybrid multilayered structures composed of alternated CdSe NCs and poly(p-styrenesulphonic acid) obtained by LBL. We found evidence of the long-lived charged surface states in the LBL film.Density functional calculations also indicate that these states are localized close to the nanoparticle surface.
