Abstract:

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 Na0.5Bi0.5TiO3-BaTiO3 (NBT-BT) ceramics prepared by using spark plasma sintering. Under visible light illumination (405, 520 and 655 nm, respectively), the Na0.5Bi0.5TiO3-Ba(Ti0.5Ni0.5)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.

Key words: ferroelectric material, photostriction, visible light response, perovskite
