Nejat] We studied the excitation-power-dependent red shift and broadening of the emission spectra of monodisperse CdSe/ZnS quantum dot solids when they are in close proximity of gold metallic nanoparticles. Our results suggest that these features are the signs of plasmonic enhancement of the interdot energy transfer in such solids leading to (a) efficient funneling of excitons to the locations where quantum dots with large CdSe cores are and (b) near complete depletion of excitons in regions where the quantum dots with incomplete shells or/and small core sizes are located. We studied the impacts of the heat generated by the metallic nanoparticles and discussed the effects of excitation-power-dependent photoionization rates. The uneven spatial distribution of excitons in monodisperse quantum dot solids in the presence of metallic nanoparticles suggests that plasmonic fields can drive significant spatial migration of energy in such structures.
