Core-level and valence-band electronic structures of Bi2Sr2Cal-xYxCu2Oy (x=0,O.4, and 0.7) have been studied by X-ray and UV photoemlsslon spectroscopy. A Fermi edge is observed for x=0.4 as well as for x=0. It is found that the density of states at the Fermi level and the intensity of a 1.2-eV peak
