Synthesis And Characterization of ferroelectric material (Na0.5Bi0.5)TiO3- Eu2O3.
Masters thesis, Indian Institute of Technology Hyderabad.
Abstract
Lead free Na0.5Bi(0.5-x)EuxTiO3 ceramics were prepared by solid state reaction route taking five different composition with x=0.005,0.01,0.02,0.03,0.04 and 0.05 . From XRD pattern it is comfirmed that theNBT-Eu single phase were formed at differnt Eu2O3 doping. RAMAN pattern shows roughness or irregularity due to the data taken at high resolution . From morphological study by SEM it
is found that the grains were well developed and have the dense structure. Also the grain shape changes from granular to plated with increase in concentreation of Eu2O3. From UV-VIS SPECTROSCOPY it is observed that the band gap increase with increase Eu2O3 concentration. The PE-LOOP analysis shows that the remnant polarization (Pr) and coercive field (Ec) values increase with increase in
concentration. The dielectric constant increases with increase in tempreature also the broadening of the
peaks is observed with increase in concentration.
