Abstract

The present proposal aims to study nanostructured ceramic materials of n-type semiconductor oxide systems of great technological interest, such as ZnO and SnO2, deposited in the form of films on substrates, for applications as gas sensors. The synthesized materials will have their structural and morphological properties characterized by atomic force microscopy (MFA), scanning electron microscopy (SEM), scanning electron microscopy with field emission electron gun (FEG-MEV) and X-ray diffraction (XRD). Nanomaterial films will be grown with control of chemical homogeneity and microstructure on silicon, alumina or glass substrates coated with indium or fluorine doped tin oxide (ITO or FTO), during the synthesis process, or will be deposited after synthesis through spin coating or tape casting. Therefore, by controlling the synthesis, phase crystallization and sintering, it is expected to process films with higher sensing properties than conventional ceramics. The performance of the sensor films (sensitivity, response speed, selectivity, stability) will be evaluated in a hermetic chamber with controlled atmosphere and temperature. (AU)
