Structural, optical and gas sensing properties of barium titanate surface modified by nano silver

Paper represents the results of SO2 sensing performance of BaTiO3 surface modified by nano silver. Surface modification was performed by dipping of BaTiO3 thick films in the synthesized nano silver. The main objective was to investigate the effect of nano silver on gas sensing performance of BaTiO3 perovskite. Different intervals of dipping time were used to find the optimum dipping amount on the surface of perovskite oxide. Synthesized silver was characterized by UV-visible spectroscopy and transmission electron microscopy. Surface modified thick films were analyzed for structural, morphological, electrical and gas sensing properties by XRD, SEM with EDX, static gas sensing unit respectively. Selectivity of surface modified BaTiO3 thick films was also investigated
