“…The formation of the cubic BaSnO 3 (Pm3m) was observed at 600°C besides a small amount of SnO 2 and BaCO 3 , which is in agreement with the TG/ DTG analysis shown in figure 1. This crystallization temperature below 600°C is quite low compared with other synthesis methods as solid state reaction [30][31][32][33] . No significant change was observed with temperature increase from 600 to 800 °C.…”

In the last ten years, stannates with perovskite structure have been tested as photocatalysts. In spite of the ability of perovskite materials to accommodate different cations in its structure, evaluation of doped stannates is not a common task in the photocatalysis area. In this work, Fe 3+ doped BaSnO 3 was synthesized by the modified Pechini method, with calcination between 300 and 800°C/4 h. The powder precursor was characterized by thermogravimetry after partial elimination of carbon. Characterization after the second calcination step was done by X-ray diffraction, Raman spectroscopy and UV-visible spectroscopy. Materials were tested in the photocatalytic discoloration of the Remazol Golden Yellow azo dye under UVC irradiation. Higher photocatalytic efficiency was observed under acid media. As no meaningful adsorption was observed at this condition we believe that an indirect mechanism prevails. Fe 3+ doping decreased the band gap and favored the photocatalytic reaction, which may be assigned to the formation of intermediate levels inside the band gap.

“…Licheron et al, reported a superconducting behavior of Ba(Sn0.7Sb0.3)O3 sample [20]. Singh et al, reported the dielectric properties of La doped BaSnO3 and found that the remnant polarization and the coercive field decreases with increase of La in the lattice [21]. To the best of our knowledge, detailed structural analysis using the Rietveld analysis of XRD, and measurement of nonlinear optical absorption and dielectric properties, are not reported so far for Fe doped BaSnO3.…”

Doping at the possible A or B site in the ABO3 perovskite can alter the structural, morphological and optical properties of the compounds. Perovskite alkaline earth stannate BaSnO3 doped with Fe resulted in BaSn1-xFexO3 compounds having different concentrations (x=0.00, 0.01, 0.02, 0.03, 0.05 and 0.07) were prepared by solid-state method. The Rietveld analyzes were performed to determine the phase purity and the changes in structural parameters. Morphological analysis identifies the formation of hexagonal nanorods with doping. The non linear optical property of the prepared samples shows optical power limiting behaviour. Magnetic property signifies the existence of ferromagnetic order and EPR studies reveal the possible ferromagnetic ordering of Fe doped samples. Dielectric loss decreases with Fe doping and has a gradual decrease in the higher frequency regime and has applications in high frequency devices.
