Photostrictive materials exhibit great potential in the light-driven microactuators/sensors, light-controlled microrobots, and other optomechanical applications. In this study, we present the photostrictive performance of Ni-modified Na_0.5Bi_0.5TiO₃-BaTiO₃ (NBT-BT) ceramics prepared by using spark plasma sintering. Under visible light illumination (405, 520 and 655 nm, respectively), the Na_0.5Bi_0.5TiO₃-Ba(Ti_0.5Ni_0.5)O₃ (NBT-BNT) ceramics exhibits large photostriction of the order of 10 ^-3 and photostriction coefficient around 10 ^-11 m ³/W. The XRD peaks of the sample under external illumination show low angle shift, indicating the light-induced lattice distortion, which contributes to the large photostrictive response of NBT-BNT ceramics.
