La0.8Pb0.1Ca0.1Fe1−xCoxO3 thin films as ozone-sensitive layers

Résumé

This paper describes the realization and characterization of La0.8Pb0.1Ca0.1Fe1−xCoxO3 gas-based sensors. La0.8Pb0.1Ca0.1Fe1−xCoxO3 (0.00≤x≤0.20) thin films are prepared using the drop-coating method over a Si/SiO2 substrate with inter-digitated Pt-electrodes. The sensors, thus, produced exhibit a good sensitivity to ozone at low concentration. The substitution of iron atoms by cobalt ones increases the sensor responses “S,” from 1.716 for x=0.00 to 6.584 to x=0.20 for an ozone concentration equal to 400ppb. In addition, the substitution of iron by cobalt induces a decrease in the sensor-operating temperature from 270∘C for the parent compound (x=0.00) to 170∘C for x=0.20.
