Abstract
In the present work, we investigate the electronic structural microstructure and spectroscopic characteristics of LuFeO3. Sample is prepared by the solution combustion method. X-ray diffraction patterns of LuFeO3 nanoparticles confirm the orthorhombic structure crystallite size found in nano range. X-ray photoelectron spectra were excited with a monochromatized AlK-line radiation. Absolute resolved energy interval was 0.6 eV, which was determined with the Ag3d5/2 line. The diameter of the X-ray spot on a sample was 500 mkm; it was small enough to study the samples obtained Mössbauer spectra of LuFeO3 were collected in the temperature range of 13–700 K. At 700 K, the spectra of both samples are paramagnetic doublets with similar parameters. At the lowest temperature (14 K), the spectra of both samples are magnetically split sextets. The isomer shift values of the sextets and doublets are typical for Fe3+ ions in oxygen octahedron. Morphology study and elemental analysis results reveal that the particle morphology and size is highly dependent on the reaction temperature, synthesis method, and fuel. Further, the active vibrational bands in these spectra correlate to the functional groups found in the examined system.
