Abstract
We have investigated the optical properties of CdSe/ZnS core-shell quantum dots (QDs), perturbed by the presence of a patterned film of size-selected gold nanoclusters. Quenching of the fluorescence emission of the quantum emitters was observed as a function of the distance between the metal nanoparticles and the QDs. Long-range quenching was observed up to distances of similar to 100 nm, which we attribute to a field-enhancement effect caused by the small size-selected clusters (
