Microwave Combustion Synthesis of La1-xGdxFeO3 (x = 0 to 0.25) Nanoparticles: Structural, Magnetic, Vibrational, Morphology and Optical Behavior

La 1 -x Gd x FeO 3 ( x  = 0 to 0.25) nanoparticles are prepared by microwave combustion process (MCP) with L-alanine as a fuel. The synthesized samples were characterized by XRD, TEM, SAED, XPS, FE-SEM, EDX, FTIR, DRS-UV and VSM analysis. XRD and FT-IR confirmed that lanthanum ferrite has an orthorh...

Description
Summary:La 1 -x Gd x FeO 3 ( x  = 0 to 0.25) nanoparticles are prepared by microwave combustion process (MCP) with L-alanine as a fuel. The synthesized samples were characterized by XRD, TEM, SAED, XPS, FE-SEM, EDX, FTIR, DRS-UV and VSM analysis. XRD and FT-IR confirmed that lanthanum ferrite has an orthorhombic structure with an average crystallite size ranging from 57.8 to 37.9 nm. The energy gap values were estimated using UV–vis spectra and it is in the range between 2.17 and 2.43 eV. The elements Gd, La, Fe and O are present in EDX and XPS analysis. FE-SEM images reveal aggregated spherical morphology. VSM analysis shows strong ferro magnetic behavior of La 1 -x Gd x FeO 3 nanoparticles. The M s and M r values are in the range between 5.63 to 6.54 and 0.76 to 1.71 emu/g for La 1 -x Gd x FeO 3 respectively. The experimental results of this work hold promise for further advancements and novel uses in various fields of technology and industry, include solid oxide fuel cells, oxygen separation membranes, gas sensors, catalysis, magnetic devices, electrochemical devices, and potential use in environmental and thermoelectric applications.
