Electrical characterization of room temperature humidity sensors in La0.8Sr0.2Fe1−xCuxO3 (x=0, 0.05, 0.10)
Semiconducting oxide gas sensors based on La0.8Sr0.2Fe1−xCuxO3 (x=0, 0.05, 0.10) (LSF, LSFC05, and LSFC10, respectively) were prepared by screen-printing for humidity detection at room temperature. The thick-films were heat-treated at 800, 900 and 1000°C for 1h and all the compositions proved to be...

| description | Semiconducting oxide gas sensors based on La0.8Sr0.2Fe1−xCuxO3 (x=0, 0.05, 0.10) (LSF, LSFC05, and LSFC10, respectively) were prepared by screen-printing for humidity detection at room temperature.
The thick-films were heat-treated at 800, 900 and 1000°C for 1h and all the compositions proved to be effective in humidity sensing and presented a good reproducibility between several measurements. However, the best results were obtained with LSFC10 fired at 800°C which showed a detection limit of 15% relative humidity and a maximum sensor response of about 87%, higher than the previous results. Copper addition to lanthanum strontium ferrites proved to be effective in lowering the sensors’ detection limit. |
