Ultraviolet and X-ray photoemission spectroscopic (UPS and XPS) studies to characterize the electronic structure of bismuth cuprate superconductor with nominal composition of Bi1.8Pb0.4Sr2Ca2.2Cu3O10 have been carried out. The data clearly shows the metallic emission at the Fermi level (EF). The shoulder (-1.2 eV) near the EF is attributed to the Cu-O derived states. Cu satellite structures observed both in the UPS and XPS show the strongly correlated nature of the Cu 3d electrons. Core level shifts indicate that 3+ and 4+ are the main oxidation of Bi and Pb, respectively. The Pb core lines show two components indicating their inequivalent sites. Core level O 1s spectrum is deconvoluted to show the presence of structurally non-equivalent oxygen sites.
