| description | The solid solution of Sr0.7Bi0.2(Ti1-xZrx)O3 0.0 ≤ x ≤ 0.6 ceramics has been prepared by mixed oxide route. In this work, the impact produced by doping Zr4+ on the structural, optical, morphological, magnetic and dielectric properties of Sr0.7Bi0.2(Ti1-x Zrx)O3 ceramics has been investigated with respect to the frequency range of 1KHz to 1 MHz. According to the X-ray diffraction patterns, the base sample is a member of the space group pm-3 m and has a cubic structure. Using a scanning electron microscope (SEM), the samples' surface appearance and average grain size (0.493–0.381 μm) were examined. The difference of ionic radius between Ti4+ and Zr4+ ions have been observed to cause a decrease in grain size with Zr4+ doping. The FTIR study confirms the presence of metal‑oxygen bond and functional groups. The observed peak emission at 710 nm corresponds to the excitation energy of 1.76 eV in photoluminescence spectra. The UV visible absorption spectra results, the band gape energy (Eg) drops from 4.83 eV to 4.43 eV with an increasing the Zr4+ contents. The magnetic properties of Sr0.7Bi0.2(Ti1-xZrx)O3 0.00 ≤ x ≤ 0.60 ceramics at room temperature is increases with Zr4+ content, due to lattice distortions, improved exchange interactions, and oxygen vacancies that facilitate magnetic ordering, In addition to increasing domain wall pinning, Zr4+ doping decreases the grain size, which qualifies these ceramics for use in electromagnetic devices and magnetic storage. The dielectric properties of the prepared samples were strongly dependent on the frequencies, temperature, and as well as on concentration. The dielectric constant's temperature and content variations are most likely caused by the charge carrier hopping process and thermally induced dipolar relaxation. The overall best results are appropriate for applications using wireless devices. |
