Eco friendly (Na0.5Bi0.48Eu0.02) Ti1-xNbxO3 ceramics were synthesized with help of conventional solid state reaction by using high energy ball milling. The room temperature XRD of Nb5+ substituted NBET ceramics were stabilized in single phase pervoskite structure without any secondary phase. Polarization study reflects long range ferroelectric order for pure NBET ceramics and coercive field enhance with the substitution of Nb5+ ion at Ti site. Further, the substitution of Nb5+ ≥ 0.02 composition induced relaxor future. The energy density calculation shows the maximum energy storage density of 1.02 J/cm3 for x=0.02 ceramics. These results confirms a small fraction of Nb5+ doped NBET ceramics should be good candidates for energy storage applications.
