资源简介：
La-Sr-Ce-Ni-Ti (LSCNT) based ceramics sample was manufactured by standard solid state reaction.Prepared powder was pressed into pilled and sintered in a furnace in air atmosphere for 10h. Annealing temperature was 1200 Celsius degree. To calculate chemical composition and determine valence states of the elements, X-Ray photoemission spectroscopy (XPS) analysis were performed. Measurements were conducted at room temperature under a pressure below 1.1 × 10−9 mBar. The photoelectrons were excited by an Mg-Kα X-Ray anode operated at 15 keV and 300 W. Omicron Argus hemispherical electron analyser with a round aperture of 4 mm was used for the analysis of energy of the emitted photoelectrons. Th high resolution scans were performed for each element (La3d, Ni2p, Ti2p, Sr3d and Ce3d).
