Document Abstract
This research investigates the structural, dielectric, and optical properties of doped barium titanate
(BaTiO3) ceramics, highlighting their potential for advanced electronic applications. Barium titanate, a
prominent ferroelectric material, was doped with various elements in a systematic manner to improve its
functional attributes.The crystalline structure and phase development were described by means of X-ray
diffraction (XRD), showcasing how doping affects lattice parameters and phase stability. Dielectric
characteristics like loss tangent and permittivity were evaluated across different frequencies and
temperatures, revealing the dopants' impact on dielectric behavior and ferroelectric properties. Optical
studies, including UV-Vis spectroscopy, examined the bandgap and optical transmittance, which are vital
for optoelectronic uses. It is found that targeted doping can effectively modify the structural, dielectric,
and optical characteristics of barium titanate ceramics, making them ideal for capacitors, sensors, and
other electronic devices. This study offers valuable insights into optimizing barium titanate ceramics to
achieve superior performance in various technological applications. It has also been observed that
certain dopants reduced the bandgap energy, leading to better optical transparency and tunable refractive
indices, which are valuable for optoelectronic applications.
