Abstract Spectra for the filled and unfilled electronic states of the (Bi,Pb)-2223 high temperature superconductor were recorded by photoemission and fluorescence X-ray absorption in the entire doping range achieved by substitution of bivalent Ca ions with trivalent Y. In photoemission these samples show diminishing spectral intensity near E F and at 1.5 eV binding energy with increasing Y content. Parallel to the observations for the filled states the O1s X-ray absorption spectra show a decrease and a shift to higher energies of the empty states just above EF The spectral structures are identified in the framework of the Hubbard model.
