Abstract
In present investigation, nanostructured CdSnO3 and Zn doped CdSnO3 were deposited
onto heated glass substrate by simple spray pyrolysis (SP) technique. Sensing elements of
nonostructured CdSnO3 and Zn doped CdSnO3 were annealed at 500 0C for 1 hrs. Characterization
includes a different analytical technique such as, X-ray diffaractogram (XRD), energy dispersive X-ray
analysis (EDAX), Field emission scanning electron microscope (FE-SEM), Transmission electron
microscope (TEM) and UV–VIS absorption spectroscopy. The average crystallite size and grain size
observed from XRD and FF-SEM was found to be increased with increase in volume % of Zn in
CdSnO3. The films volume 5 % of Zn in CdSnO3was observed to be most sensitive (S = 1230) to
ethanol for 500 ppm at 300 0C. The response and recovery time is 5 sec, 7 sec respectively. The results
are discussed and interpreted.
