Description
Strontium titanate (SrTiO₃) is a perovskite oxide with excellent dielectric and optical properties, making it a promising material for photocatalytic, sensing, and optoelectronic applications. This study investigates the effect of Ferrum (II) acetate doping on the crystal structure and optical properties of SrTiO₃ ceramics synthesized using the conventional solid-state reaction method. Ferrum (II) concentrations of 0, 0.5, and 1.0 wt.% were introduced into the SrTiO₃ matrix, followed by annealing at 850 °C for 8 h. The synthesized ceramics were characterized using X-ray diffraction (XRD), and UV–Visible spectroscopy (UV–Vis). XRD analysis confirmed that all samples retained a single-phase cubic perovskite structure, while the lattice parameter gradually decreased from 3.909 Å to 3.899 Å with increasing dopant concentration, indicating successful incorporation of Fe ions into the crystal lattice. Furthermore, UV–Vis analysis demonstrated a gradual reduction in the optical bandgap from 3.54 eV to 3.23 eV as the dopant concentration increased. The observed lattice contraction and bandgap narrowing indicate that Ferrum (II) acetate doping effectively tailors the structural and optical characteristics of SrTiO₃ ceramics, highlighting their potential for future optoelectronic, photocatalytic, and semiconductor applications.
