Abstract Perovskite oxide materials, specifically MgTiO 3 (MT) and Li-doped (MTxLi), were synthesized via a sol–gel method calcination at 800 °C. This study explores the impact of varying Li doping levels (x = 0, 0.01, 0.05, 0.1) on crystalline structure properties . X-ray diffraction analysis revealed well-defined rhombohedral phase. Optical diffuse reflectance measurements provided insights into energy gap values, refractive index, dielectric constant. + enhanced electrical , with notable...
Abstract Talented di-phase ferrite/ferroelectric BaTi 0 . 7 Fe 3 O @NiFe 2 4 (BFT@NFO) in oval nano-morphology was chemically synthesized using controlled sol–gel processes and calcined at 600 °C. The effects of shielding NiFe (NFO) nanoparticles on the microstructure, phase transition, thermal, relative permittivity (BTF) nano-perovskite were systematically explored. X-ray diffraction patterns Full-Prof software exhibited forming 11 hexagonal phase. TEM SEM images demonstrated that coating...
Abstract In this paper, we present a humidity sensing material based on nanostructured Zn (1.6 − x) Na 0.4 Cu x TiO 4 spinel to enhance optical and sensitivity performance. Nano-porous of were synthesized using sol gel reactions calcined at 700 °C. The nanostructures underwent thorough characterization through multiple techniques. X-ray diffractometry (XRD) coupled with Rietveld refinement FullProf software, transmission electron microscopy (TEM), Raman Spectroscopy, analysis employed assess...
Synthesis, morphology control, and diffuse reflectance of Fe/Al/Si/Cu–ZnTiO3 prepared using the sol-gel method calcined at 750 °C have been inspected. The Fe, Al, Si, Cu can interchange Ti ions form sols in ZnTiO3 matrix. microstructural optical properties were affected by dopant.
