Going dotty : Nanosphere lithography has been used to define silver islands on which self‐assembled monolayers of thiol linkers followed by CdSe@ZnS quantum dots (QDs) were deposited. Up to five further layers of linkers/QDs were added. The multiple layers cause a monotonic but nonlinear increase in film luminescence emission intensity. The image shows such an array of QDs, as imaged by confocal microscopy.
