Abstract
Abstract Lead-free ferroelectric [(Bi0.5Na0.5)0.94Ba0.06]1−xLaxTiO3 (BNBT-100xLa, 0≤x≤0.05) ceramics were prepared by the solid state sintering methods and the effects of La3+ doping on ferroelectricity and electromechanical strain were systematically investigated. The X-ray diffraction analysis revealed that the crystal structure partly transformed from rhombohedral phase to tetragonal phase with the increasing of La3+ donor doping. The long-range FE order dominant in pure BNBT was disrupted by La3+ doping. For BNBT-3La, the largest maximum strain Smax was 0.53% with a high normalized strain d*33 of 707 pm/V under 75 kV/cm at room temperature. Moreover, a phase transition happened at EF=46.06 kV/cm under the cycle of 75 kV/cm. In particularly, a slim and pinched P-E loop was obtained for BNBT-5La with a large energy density of 1.66 J/cm3 at 105 kV/cm.
