Abstract The Bi2Sr2CaCu2O8+δ system samples doped with Pr on Ca sites were synthesized. Resistivity temperature dependence, X-ray powder diffraction, and photoemission experiments have been performed. Both X-ray diffraction and photoemission measurements show that Pr ion enters the lattice with a valence higher than 3+, which supports the hole-filling mechanism of the suppression of superconductivity.
