Ferroelectric and Optical Properties of Tantalum Doped Srbi4ti4o15

This paper presents the effect of Tantalum doping on bismuth layered SrBi4Ti4O15 (SBTi) ferroelectric oxide. The ceramics with nominal formula SrBi4Ti4-xTaxO15(x=0,0.05,0.15,0.25) was prepared by solid state reaction technique. The ferroelectric and optical studies were performed using ferroelectric hysteresis loop and Diffused Reflectance spectrum, respectively. It was found that the tantalum doping has not much effect on the band gap values, but it decreased the remnant polarization of SBTi ceramics. Keywords- Solid state reaction, Ferroelectric.
