An eco-friendly synthesis of barium strontium titanate nanoparticles: Investigation on tin doping on structural and optical properties.

This article reports a simple and green synthesis employed solid state reaction method was used to prepare the Perovskite-type pure and tin doped barium strontium titanate (BaSrSnTiO3) nanoparticles with Moringa oleifera leaf extract as capping agent. BST and BSST nanoparticles were characterized by XRD, SEM with EDAX, FTIR, UV, PSA and EIS techniques. The structural, morphological, optical and electrical behaviours of BST and BSST nanoparticles are elaborately discussed. The development of a single-phasic cubic perovskite structure with no impurity phases BST and BSST nanoparticles is revealed by XRD study. The formation of perovskite structure was demonstrated by an observable band in lower frequency ranges in an FTIR analysis. The crystallite size was determined using Debye Scherrer analysis. The findings show that the green synthesis of BST has strong crystalline, optical, and electrical properties, and that these properties can be tailored using tin doping with BST.
