Abstract

An x-ray photoemission spectroscopy study of the blue molybdenum bronze K0.30MoO3 shows a conduction band of Mo 4d character extending 2 eV below the Fermi level. The valence band lies between 2 and 10 eV. The Mo 3d core-electron spectrum has components at binding energies previously identified with Mo5+ and Mo6+ ions in related molybdenum oxide compounds. In this metallic system these two states are, however, of final-state origin, representing alternate screening channels and do not indicate that discrete valences are present in the initial state.
