- Abstract
In this work, we report the influences of Ce doping on structural, morphological, optical and charge derived properties of BaTiCeO (x = 0.02, 0.04, 0.06 & 0.08) ceramic synthesized by high temperature solid state reaction method. This ceramic has been characterized by powder X-ray diffraction (PXRD), UV-visible spectrometry, scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). Lattice parameters were determined through the profile refinement technique using PXRD data. Charge density redistribution and bonding nature of the grown systems are analyzed by maximum entropy method (MEM). Incorporation of rare earth ion Ce into the BaTiO lattice enhances the ionic nature between Ba and O ions and decreases the ionic nature between Ti and O ions, revealed from the qualitative and quantitative analysis by MEM. Optical band gap values are estimated for the prepared samples from UV-Vis data. Formation of aggregated particles with low porosity is observed from SEM micrographs. The chemical compositions of the prepared samples are further confirmed by EDS spectral analysis.
