Nanosize silver particles were prepared by argon ion sputtering of an island-like silver film deposited by pulsed laser evaporation onto Si(1 0 0). The changes in the electronic structure related to particle size were observed by photoelectron spectroscopy during sputtering. The changes in the valence band induced by size reduction were dominated by a strong decrease in the lowest binding energy peak of the Ag 4
d band, while other structures at higher binding energies remained unchanged. This redistribution of the
d-states in the valence band seems to be common for noble metal nanoparticles.
