For this study, Ba1-y-x Pr2y/3□ y/3(Na0.5Bi0.5) x Ti0.9Zr0.1O3 (y = 0.5%; 0.05, 0.1 and 0.15) (abbreviated as BZT-Pr-xNBT) ceramics were prepared by a solid state reaction method. The samples structurally characterized X-ray diffraction (XRD) the software Fullprof, which showed atomic positions, bond distances, angles of these materials in tetragonal structure. crystallite size, determined both Williamson-Hall Debye-Scherrer methods, increases with increasing Na0.5Bi0.5TiO3 NBT) content Ba1-y y/3Ti0.9Zr0.1O3 0.5%) BZT-Pr) ceramic. ultraviolet-visible (UV-Vis) diffuse reflectance spectrum indicated that BZT-Pr-xNBT exhibited direct band gap values range 2.90-2.78 eV. Moreover, study investigates ferroelectric, energy storage, pyroelectric harvesting properties varying NBT contents (x 0.10 0.15). results reveal substitution significantly influences ferroelectric characteristics enhances recoverable storage density (W rec) efficiency (η). Temperature-dependent scaling relations for coercive field (E C) remnant polarization (P r) derived all samples. BZT-Pr-0.15NBT ceramic, relation E C P r ∝ T -0.089, -0.233) highlights improved thermal stability composition. Pyroelectric under Olsen cycle identified BZT-Pr-0.05NBT most efficient These findings emphasize crucial impact optimizing ceramics.
