Description
Ceramics based on Barium, Lanthanum, Gadolinium and Cobaltium were produced by standard solid state reaction from oxides and carbonate powders. After sintring, samples were annealed for 2 hours or 72 hours at 300 Celsius degree in a both: wet and dry atmosphere. Results of annealing on a chemical composition and valence state of lanthanum were observed by X-Ray photoemission spectroscopy (XPS). XPS analysis were performed 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 emitted photoelectrons. Measurements were carried out in a constant analyser energy (CAE) mode with pass energy equal 50 eV. To remove contaminations and oxides, the surface was etched before the measurement. Argon ion gun with energy up to 5 keV was used for 5 min. etching. In this dataset La3d high resolution spectra for each samples are presented.
