SYNTHESIS AND CHARACTERIZATION OF LA2FEMNO6 NANOPARTICLES AT LOW TEMPERATURE

Abstract

The synthesis, structure and characterization of La2FeMnO6 nanoparticles were studied using a simple low
temperature method at 600°C. The sample preparation involves formation of a homogenous solution, followed by gelation
and grinding with final calcinations. On ignition in air, the compound is found to transform into nanosized La2FeMnO6
nanoparticles. The analysis of X-ray diffraction (XRD) data confirmed the monoclinic La2FeMnO6 perovskite of space
group P21/n without any impurity phase. The Scherrer’s formula was employed to estimate the crystal size of the prepared
sample. For a further insight into the crystal structure, Scanning electron microscopy (SEM) imaging was done. The
estimated values of the crystal size from Scherrer’s formula and SEM were found to be roughly the same. The SEM
images confirmed the polycrystalline nature of the prepared sample. Furthermore, UV measurements were performed on
the compound to estimate its band gap energy. The values were found to match well with those reported elsewhere in
literature.EDX measurements performed on the sample indicated the presence of La, Fe, Mn and O elements.
