Abstract
LaGaO3 doped on A-site and B-site with different amounts of strontium and iron, respectively (La0.8Sr0.2GaO3-δ, La0.6Sr0.4GaO3-δ and LaGa0.8Fe0.2O3, LaGa0.4Fe0.6O3) as well as a doubly doped LaGaO3 perovskite (La0.8Sr0.2Ga0.8Fe0.2O3-δ) have been synthesized by citrate gel method. The present work focuses on the XPS analysis. In particular, the effects of dopants and dopant concentrations on the LaGaO3 surface properties have been investigated and discussed. Besides the wide scan spectrum, detailed spectra for the La 3d, Ga 2p3/2, Sr 3d, Fe 2p, O 1s and C 1s regions and related data are presented and discussed.
