Popis: Ensembles of size-selected silver nanoparticles (NPs) deposited on nanostructured graphene using cluster beam technique are studied. Graphene is nanostructured by focused ion beam (FIB) to form arrays of holes. It is found that the deposited NPs are tended to collect in and around the holes in graphene. The graphene with NPs is covered by Rhodamine 6G and examined by Raman spectroscopy. It is shown that amount of so-called hot spots increases dramatically for the nanostructured graphene with Ag NPs in comparison with continuous graphene covered by the NPs at the same conditions. Hereby, combining 2D material, FIB and cluster beam deposition techniques allows to form nanostructured surfaces with advanced plasmonic properties to be applied in sensor technologies and surface enhanced Raman scattering.
