Fast response and highly selective nitrogen dioxide gas sensor based on Zinc Stannate thin films M.A. Patil, V.V. Ganbavle, K.Y. Rajpure, H.P. Deshmukh, S.H. Mujawar Materials Science for Energy Technologies, 2020 NO2 sensors based on Zn2SnO4 (Zinc Stannate) films were synthesized using spray pyrolysis method. The effect of substrate temperature (phase formation) on NO2 response is studied. XRD, SEM and AFM techniques were used to study structural, morphological and topographical analysis of the films, respectively. Zn2SnO4 films exhibits polycrystalline nature having cubic inverse spinel crystal structure. SEM and AFM studies show that the film deposited at 400 °C possess flakes like morphology and the voids present in the surface increases the roughness. Zn2SnO4 sensor shows highest sensor response of 29.3 at moderately low (200 °C) operating temperature towards 40 ppm NO2 concentration. As low response time as 8 s and recovery time of 58 s are recorded for the sensor at its highest response. The pristine Zn2SnO4 films show outstanding gas sensing properties and demonstrated excellent response and recovery kinetics without any surface modification by noble metal or surfactant.
