英文摘要	Valence band structure of Sm-intercalated C-60 thin films is researched with tutraviolet photoelectron spectroscopy and synchrotron-radiation photoermission spectroscopy. Most valence electrons of Sm transfer to C-60 and the bonding nature is mainly ionic. No Fermi edge is observed for all stoichiometries. Thus the superconducting Sm fulleride has semiconducting property at room temperature. Density of states near the Fermi level is obtained for single phase Of SM2.75 C-60. Photoemission of the solid solution phase differs apparently from that of SM2.75 C-60 . SM C-60 (2.75 < x < 6) is not the mixture of phase-separated SM2.75 C-60 and Sm-6 C-60, which indicates that another phase exists or Sm doping proceeds smoothly through the LUMO + I band. The interfaces between different phases are unstable above 130 degrees C.
