X-ray photoelectron spectroscopy of Sm-doped layered perovskite for intermediate temperature-operating solid oxide fuel cell

Chemical states of Sm doped layered perovksite, SmBa1-x Sr x Co2O5+d (x =0 and 0.5), have been investigated by X-ray Photoelectron Spectroscopy (XPS). Substitution of Sr in SmBa1-xSr x Co2O5+d oxide system shifts the binding energy of Sm 3d5/2 to the more positive side and the charge state of Sm rem...
