Nanocubes SnO2 Thin Films for the Detection of CO Gas

Abstract

Nanocubes SnO2 thin films have been prepared by spray pyrolysis method, under optimized conditions. The as prepared thin films were investigated by using X-ray diffraction, Field emission scanning electron microscope, Energy dispersive X-ray analysis, Transmission electron microscopy and Surface area electron diffraction pattern to know crystal structure, surface morphology, constituents of the elements and microstructure properties. The gas sensing performance was studied as a function of operating temperature. CO gas detection was also investigated with stability of thin films were studied and discussed.
