Under illumination by 405, 520 and 655 nm monochromatic visible light (light intensity of 30 kW/m 2 ), large photostriction (Δ L/L ) of 0.19%, 0.13% and 0.26% for 67BiFeO 3 -33BaTiO 3 (67BF-33BT) lead-free ferroelectric ceramics are obtained, respectively. By studying the ferroelectric and photoelec...
