Ultrasonically Sprayed Nanostructured Perovskite-Type CdSnO3Thin Films for Sensing of CWA Simulants

Abstract

CdSnO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> thin films were prepared using ultrasonic spray pyrolysis technique. The structural, microstructural, and optical properties of the films were studied using X-ray diffraction, transmission electron microscopy, and UV-VIS spectroscopy, respectively. The sensing performance of a typical film was tested for chemical warfare agent simulants, such as, 2-chloroethyl ethyl sulfide C <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">9</sub> ClS CEES (CEES), dimethyl methyl phosphonate C <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">9</sub> O <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> P (DMMP), and 2-chloroethyl phenyl sulfide C <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">8</sub> H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">9</sub> ClS (CEPS). The simulant sensing performance of CdSnO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> thin-film-based sensor was tested. CdSnO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> thin-film-based sensor was observed to be more sensitive to CEES as compared with DMMP and CEPS. The results were discussed and interpreted.
