The Influence of Water-to-Surfactant Ratio on the Synthesis and Characterization of LaFeO₃ Ortho-Ferrite Nanoparticles

.Lanthanum orthoferrite perovskite-type LaFeO3 (LFO) was successfully synthesized at room temperature (RT) using the reverse micelle method (RM) with different water-to-surfactant ratios. Into the implementation of this study, we used various characterization techniques such as the Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) measurements, ultraviolet-visible (UV-Vis) spectroscopy, and dielectric and impedance spectroscopy LCR meter. TGA and DSC measurements were used to determine the LFO thermal properties. UV-visible is used to examine the various optical properties of LFO such as optical bandgap energy (E_g), absorption and extinction coefficients, Urbach energy (Eu), and threshold wavelength. The dielectric properties and impedance spectra were also studied in detail.
