Description

An X-ray photoelectron spectroscopy study of Na-doped Bi-2212 cuprates is reported. Core level photoemission spectra were collected, at different take-off angles, from a monophasic crystal. The results of the lineshape analysis and the dependence of the core line intensity on the analyser take-off angle allowed them to rule out the presence of Na within the Bi-O layers, indicating that Na+ is very likely replacing Ca2+ or Sr2+ ions
