Abstract

The Cu (3d-4s→2p3/2)Lα X-ray emission band has been measured in Cu nanoclusters, present in a series of Cu/C60 thin-film nanostructures. In comparison with bulk Cu, a negative shift and a narrowing of the Lα band have been noticed. These observations are mainly attributed to a size effect but charge transfer from metal to C60 occurring at interfaces and causing a depletion of the Cu 3d band is also considered.
