Abstract

The structural and dielectric properties of La1-xBixFeO3 ceramics (x = 0, 0.025, 0.05, 0.10, 0.15), synthesized via the sol–gel method, were investigated to assess their potential for electronic applications. X-ray diffraction (XRD) and Rietveld refinement confirmed a single-phase orthorhombic structure (Pbnm), with an increase in crystallite size from 32.25 to 55.58 nm and minimal lattice distortion due to the comparable ionic radii of Bi3+ and La3+. Raman spectroscopy revealed shifts and broadening in low-frequency Ag modes (
