ABO 3 perovskites show unusual property modifications by proper substitution at the A and B sites. Polycrystalline perovskite BaSnO 3 samples doped with different concentrations of manganese (BaSn 1− x Mn x O 3 ) were synthesized by solid-state reaction method. Rietveld refinement of XRD analysis confirmed the structure and phase purity of the synthesized compound. Diamagnetic-to-paramagnetic transition and optical bandgap tuning indicate the substitutional effect of Mn in the host BaSnO 3 lattice. The strong reverse saturable absorption of the synthesized samples makes them ideal candidate for optical limiting applications. The frequency and composition-dependent dielectric studies reveal that Mn-doped BaSn 1− x Mn x O 3 can be used for high-frequency device applications. The cycling retention in the specific capacitance of 96.2% at a current density of 25 mA/g even after 2500 cycles in Mn-doped BaSnO 3 electrode can be used in energy storage devices for supercapacitor applications.
