The LaSrZrFeO6 powder was synthesized using a conventional solid-state reaction process. The qualitative phase analysis through X-ray Diffraction (XRD) and data analysis with Rietveld refinement confirm the single-phase formation of a novel double perovskite. Crystal structure investigation was conducted to determine the lattice parameters, bond lengths, angles, and ions distribution. Additionally, crystallite size, lattice strain, density, and porosity were calculated. Fourier-transform infrared (FTIR) spectroscopy has been performed to examine the vibrational modes and bond formations in the sample. The sample's microstructure, including grain shape and size distribution, and elemental composition, were assessed using Field Emission Scanning Electron Microscopy (FE-SEM) and Energy Dispersive X-ray (EDX) analysis. The optical energy bandgap of the material, determined to be 2.81 eV, was ascertained through UV-visible absorption spectroscopy. Furthermore, the refractive index was calculated using both the Moss and the Herve and Vandamme methods. The study also delved into the electrical characteristics of the material, such as permittivity (εr), loss tangent (tanδ), and conductivity (σ). These properties were analyzed in relation to changes in frequency and temperature, employing particular formulas and parameters for a comprehensive understanding.

NdCrO3 perovskite compound was synthesized via sol-gel auto-combustion process and the impedance spectroscopic data was studied in the wide frequency range (0.1Hz -10MHz), at various temperatures (RT-500°C). Structural analysis was done using Raman spectroscopy, which indicated single-phase orthorhombic structure. Energy dispersive X-ray diffraction and X-ray photoelectron spectroscopy showed Nd, Cr, O elements in the NdCrO3 compound, suggesting that the sample was pure. Scanning electron microscopy and transmission electron microscopy (TEM) analysis confirmed that the distribution of grains and particles was not uniform throughout the surface and material, respectively. TEM imaging indicated that the polycrystalline nature and particle size was on the order of 30-50 nm. This material showed the giant dielectric behavior (ε^'>〖10〗^4). Impedance studies of NdCrO3 perovskite exhibited a negative temperature coefficient of resistance type semiconductor behaviour. The dc conductivity and relaxation plots were followed by Arrhenius law. Frequency reliant ac conductivity plots followed Jonscher’s power law. These results suggest that NdCrO3 is suitable for giant capacitors applications.
