Thin films of (0.9)BaTiO3-(0.1)BaZr0.5Ti0.5O3 (BT-BZT) is ferroelectric materials developed to meet the specifications for multilayer ceramic capacitors (MLCC). This study aims to analyze the optical properties, crystal structure, morphological structure, and dielectric properties of BT-BZT using Ultraviolet-Visible (UV-Vis) spectroscopy, X-Ray Diffraction (XRD), Field Emission Scanning Electro…
