The electronic energies of lead–salt quantum dots (QDs) are determined primarily by quantum confinement due to their large exciton Bohr radii.[1] The fundamental electronic structure of the QDs (PbS and PbSe) has been worked out by Kang et al.,[2] and now research with these materials is turning towards applications. For instance, lead–salt QDs have been used as active materials in photovoltaic devices [3, 4] due to their size-tunable ...
