Defect engineering is a proven method to tune the properties of perovskite oxides. In demanding high-power piezoelectric ceramic applications, acceptor doping most effective harden ceramics, but it inevitably degrades ceramics' electromechanical properties. Herein, poling based on doping, namely, high-temperature poling, implemented by applying an electric field above Curie temperature for achieve balance coefficient d33 and mechanical quality factor Qm. After property 0.6 mol % Mn-doped Pb0.92Sr0.08(Zr0.533Ti0.443Nb0.024)O3 = 483 pC/N Qm 448. Compared with traditional ceramics increased approximately 40%, also nearly 18%. Therefore, high were exhibited our PZT ceramics. Rayleigh's law analysis, XRD, transmission electron microscopy analysis show that, after considerably related large increase in reversible domain wall motion intrinsic effect, while slightly inhibited irreversible extrinsic effect. This study reports provides insights into design
