Abstract

(Pb_1-1.5xLa_x)(Zr_0.66Sn_0.23Ti_0.11)O₃ (PLZST) ceramics with different lanthanum (La³⁺) content (x=0-6%) were prepared by conventional solid state reaction process, and exhibited excellent electrical properties with high switching field from AFE to FE phase and electric breakdown strength. The maximum dielectric constant (εm) and its corresponding temperature (T_m) decreased with La3+ doping and a phase transition from rhombohedral ferroelectric (FE) to tetragonal antiferroelectric (AFE) state was found at 2% La³⁺ doping. At room temperature, a maximum energy density of 1.47 J cm^-3 was obtained for x = 4%. In addition, electric-field-dependent energy storage properties of PLZST (x = 4%) ceramics have been investigated, which could be ascribed to the AFE-FE phase transition associated with the increase of strain.
