Abstract

Abstract: SnO2 is synthesized by microwave assisted technique. Crystal structure and particle size is studied by XRD. Particle size of synthesized sample is investigated by TEM, FE-SEM and Scherrer formula. Crystalline nature is observed by SAED. FE-SEM of sample is carried out for knowing surface morphology and particle size. Energy dispersive analysis by X-ray (EDAX) is done for studying elemental composition and their mass percentage in the sample. The thick film of SnO2 is fabricated by screen printing technique for exploring V-I characteristics and conductivity. The gas sensing response of SnO2 thick film sensor towards H2 S, LPG, NH3 and CO2 is studied
