Structural investigations of La0.8Sr0.2CrO3 by X-ray and neutron scattering

Effect of Sm3+ and Sr2+ dopants on the FT-IR, photoluminescence and surface texture of lanthanum chromite nanoparticles

“…LaCrO 3 (LC)-based compounds with the perovskite structure (ABO 3 ) are the most promising materials as interconnect for solid oxide fuel cell (SOFCs) owing to their refractory nature, corrosion resistance and the possibility of doping to promote electronic conductivity [1,2]. They are also of interest for electrode applications in magneto-hydrodynamic (MHD) generator channels and as heating elements in high temperature furnace [3,4].…”

“…Pure LaCrO 3 exhibits orthorhombic symmetry at room temperature and transforms to rhombohedral symmetry at 255 • C [3]. However, the doping of a metal cation in La-and/or Crsites of LaCrO 3 arrests the structures' transformation depending on the conditions of preparation [4][5][6]1,2,[7][8][9][10]. It was reported that undoped LaCrO 3 has a p-type semiconductor nature and their electrical conductivity is essentially due to the 3-d band of the Cr 3+ ions through the formation of cation vacancies [8].…”
