Nano-engineered electron–hole exchange interaction controls exciton dynamics in core–shell semiconductor nanocrystals
A strong electron–hole exchange interaction (EI) in semiconductor nanocrystals (NCs) gives rise to a large (up to tens of meV) splitting between optically active ('bright') and optically passive ('dark') excitons. This dark–bright splitting has a significant effect on the optical...
