The effects of Sr-substitution in Ba2SmTi2Nb3O15 ceramics: structural study, optical properties, and complex impedance spectroscopy

“…The shape of the X-ray diffraction peaks was approximated using the Pseudo Voigt function, expressed as PV = ηL + (1 − η ) G , where η is the mixing factor, G corresponds to the Gaussian function, and L represents the Lorentzian function. 34 …”

“…The shape of the X-ray diffraction peaks was approximated using the Pseudo Voigt function, expressed as PV = hL + (1 − h)G, where h is the mixing factor, G corresponds to the Gaussian function, and L represents the Lorentzian function. 34 The peak shi in the XRD is based on the dopant size. If the dopant size is smaller Sr than the base metal Ba it occupies the interstitial position leading to change in the lattice structure and the d-spacing between the atoms become less and there is an increase in the X-ray diffraction resulting in higher angles.…”

Structural, electrical, and dielectric study of the influence of 3.4% lanthanide (Ln3+ = Sm3+ and La3+) insertion in the A-site of perovskite Ba0.95Ln0.034Ti0.99Zr0.01O3

“…Subsequently, the Pseudo-Voigt function which can be written as PV = ηL + (1 − η ) G , where η is the mixing factor, G is the Gaussian function, and L represents the Lorentzian function, was used to assimilate the shape of the X-ray diffraction peaks. 59 Furthermore, the Caglioti ( U , V , W ) equation was used to describe the half-width of the diffraction peaks. 60 The starting model used to refine the composition of BZT, BSmZT and BLaZT are that of structural parameters related to the tetragonal phase of BaTiO 3 , such as space group (No.…”

Enhanced Photocatalytic Water Splitting of SrTiO3 Perovskite through Cobalt Doping: Experimental and Theoretical DFT Understanding

“…Powders of SrTi 1– x Co x O 3−δ (STCO) perovskite compounds ( x = 0, 0.125, 0.25, 0.375, and 0.50) were prepared by the solid-state reaction method using highly pure powders of strontium nitrate (Sigma-Aldrich, 99.9%), titanium(IV) dioxide (Sigma-Aldrich, 99,9%), and cobalt(II) chloride hexahydrate (Sigma-Aldrich, 99.5%) according to the stoichiometry, as shown in the following reaction: Sr false( NO 3 false) 2 + ( 1 − x ) TiO 2 + x CoCl 2 · 6 normalH 2 normalO → SrTi 1 − x Co x O 3 − δ + 2 NO 2 ↑ + 6 x H 2 O ↑ + x Cl 2 ↑ …”
