Modified Cadmium Stannate Nanostructured Thin Films Prepared by Spraying Technique for the Detection of Chemical Warfares

In present study spray pyrolysis technique was employed to prepare pure and doped CdSnO3 thin films. The spray pyrolyzed thin films were observed to be nanostructured in nature with particle size less than 10 nm and characterized to investigate its structural, microstructural and chemical properties by means of XRD, SEM/EDS, TEM and surface profilometry. Pure and Zn doped CdSnO3 nanostructured thin films were tested against THE simulants of chemical warfare agents (CWA). The Zn doped nanostructured thin films showed good sensing performance towards the simulants as compared to the pure thin films. The effect of nanocrystalline nature on simulant-sensing properties of pure CdSnO3 and Zn-doped CdSnO3 thin films was discussed and interpreted.
