The nanocrystallineLa1-xNdxFeO3(0≤x ≤1.0) powders with orthorhombic perovskite phase were prepared by sol-gel method. The average crystallite sizes ofLa1-xNdxFeO3powders are about 20 nm. The resistance and gas-sensing properties of theLa1-xNdxFeO3based sensors were investigated in the temperature range from 160 to 300°C. The results demonstrated that the resistance and response of the perovskite thick films changed with the increase of Nd content.

The Mean

The nanocrystalline powders Nd1-xCaxFeO3 prepared by sol-gel method crystallized as perovskite orthorhombic structure. The mean grain size of Nd1-xCaxFeO3 powders were about 15~ 40 nm. The conductivity of the Ca doped samples was enhanced, compared to that of the undoped. The Nd0.9Ca0.1FeO3-based sensor showed good gas sensing properties to ethanol and acetone. The responses of the Nd0.9Ca0.1FeO3-based sensor to 600ppm ethanol and acetone were about 158.4 at 220°C and 61.7 at 240°C, respectively.
