Abstract
In the present work an effort has been made to synthesize nanostrutured pervoskite ZnSnO3
using spray pyrolysis techniques for efficient sensing of H2S gas at lower operating temperature.
Sensor structure showed a better sensing response (S ~ 530) at a relatively low operating temperature
of 60 °C for 50 ppm H2S gas with the short response and recovery time 19 and 27 s, respectively.
Prepared thin films were characterized by X-ray diffraction (XRD), field emission scanning electron
microscopy (FESEM), energy-dispersive X-ray (EDAX) spectroscopy and transmission electron
microscopy (TEM). The results are discussed and interpreted.
