Abstract Barium stannate (BaSnO3) particles were synthesized using a one-step flame spray pyrolysis (FSP) method. The fabricated ceramic powders were investigated in terms of the structural, morphological, and optical properties by using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), X-Ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), zeta particle size analyzer, UV-visible spectroscopy (UV-vis) and photoluminescence spectroscopy (PL). The XRD results showed the structure of BaSnO3 crystals have been obtained when the powders were exposed at high temperature, specifically at 1200 °C. The synthesized particles in the submicron size in a range of 70-980 nm were produced. The optical band gap value of the synthesized crystals was calculated by means of reflectance spectra with the Kubelka-Munk method and found as 3.14 eV. When the powders excited at 375 nm, they exhibited emission bands in the visible and near-infrared region (NIR) of the electromagnetic spectrum. As far as we know, this is the first time BaSnO3 crystals have been synthesized using the FSP technique. In this study, the intensity- and decay time- based gas sensing properties of BaSnO3 embedded in ethyl cellulose thin films when exposed to the vapors of ethanol, acetone, and ammonia were also measured.
