Microstructural evolution of nanosized LaFeO3 powders from the thermal decomposition of a cyano-complex for thick film gas sensors

Surface Morphology-Dependent Room-Temperature LaFeO3 Nanostructure Thin Films as Selective NO2 Gas Sensor Prepared by Radio Frequency Magnetron Sputtering

“…37-1493). 34 The calculated average crystallite size for network structures is ∼89 nm and for nanocubes ∼71 nm at 350°C, almost in agreement with the results obtained from the morphological analysis.…”

Investigation on magnetic and electric properties of morphologically different perovskite LaFeO3 nanostructures

“…The peaks observed in the XRD pattern indicate that all the samples crystallize as a perovskite phase with orthorhombic structure. The lattice parameters estimated from XRD pattern was found to be a = 5.565, 5.569, 5.572 and 5.575 Å , b = 7.838, 7.843, 7.845 and 7.849 Å and c = 5.577, 5.581, 5.584 and 5.587 Å for the LaFeO 3 nanopetals, dendrites, nanorods and nanospheres, with a maximum experimental error of ±0.0003, which is in good agreement with the results reported in literature (JCPDS 37-1493) [28]. The narrow sharp peaks and the absence of impurity peaks suggest that the LaFeO 3 products are highly pure and crystalline.…”

Surface study of fine MgFe2O4 ferrite powder prepared by chemical methods

“…We have been investigating the preparation of a wide range of perovskite-type oxides by the thermal decomposition of the appropriate heteronuclear complexes [12][13][14][15][16]. It is well known that a number of perovskite-type oxides prepared in air display p-type semiconducting properties, and their conductivity increases with the adsorption of oxidizing gases, such as O 2 and NO 2 [17][18][19][20]. We have determined that the conductance change in the ppm-level of NO 2 gas is influenced by the adsorption/lattice oxygen ratio for the perovskite-type oxides [21][22][23].…”
