- W2964076229 abstract "Perovskite oxide based thin film gas sensors have long been considered as potential alternatives to commonly investigated binary metal oxides based sensors. BiFeO3, which is a prototype of p-type perovskite based semiconducting oxides, has recently drawn significant attention for its promising gas sensing characteristics. In the present work, the hydrogen sensing characteristics of calcium doped BiFeO3 has been reported by varying the film thickness, doping concentration, operating temperature, and test gas concentration. The films were deposited on glass substrates by sol-gel route using spin coating. X-ray diffraction analyses confirmed formation of phase pure films and scanning electron microscopy confirmed their uniform and dense microstructure. The Ca-doped BiFeO3 sensors exhibit higher sensitivity compared to pure BiFeO3 sensors. It is reported that the film thickness and Ca doping concentration play major role to control hydrogen sensing characteristics of the deposited films. The sensor based on 15% Ca-doped BiFeO3 sensor exhibited very high sensitivity (∼212% at 500 ppm H2), and selectivity towards hydrogen at a moderate operating temperature (∼250 °C). The enhanced gas sensing response of the doped BiFeO3 films has been attributed to the higher oxygen vacancy concentration induced by incorporation of aliovalent Ca2+." @default.
