Abstract :
CdSnO3 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 C4H9ClS CEES (CEES), dimethyl methyl phosphonate C3H9O3P (DMMP), and 2-chloroethyl phenyl sulfide C8H9ClS (CEPS). The simulant sensing performance of CdSnO3 thin-film-based sensor was tested. CdSnO3 thin-film-based sensor was observed to be more sensitive to CEES as compared with DMMP and CEPS. The results were discussed and interpreted.
