Abstract
We present optical extinction spectra of ligand-stabilized Au-clusters Au(N) with sizes of N=13 and N=55. They are compared to larger, embed ded clusters up to N=5.10(3) (diameter 5nm). The Mie resonance due to excitation of the dipole plasmon polariton vanishes with decreasing cl uster size. For N>55, this effect has recently been interpreted as cau sed by smearing out of the interband transition edge of Au.
