Abstract Using photoemission spectroscopy, we have studied the adsorption of Sm on C60 film. At the first stage of Sm adsorption, the C60 valence band shifts to the high binding energy side. The maximum shift is about 0.4eV. In the meantime, there appears a new structure at the upper side of the highest occupied molecule orbit (HOMO) band, which comes from the hybrid of the Sm 4f 5 state and C60 HOMO band. As Sm coverage increases the Sm electron is in a kind of Sm2+ state due to the forming of Sm cluster on the surface.
