LaO 0.5 F 0.5 BiS 2 nanosheets were produced by ultrasonification. A slightly reddish colloidal suspension was obtained by ultrasonification of LaO 0.5 F 0.5 BiS 2 powder in ethanol. Transmission electron microscope (TEM) images of the dried suspension indicated the nanosheet morphology of LaO 0.5 F 0.5 BiS 2 , and the electron diffraction spots indicated 4-fold symmetry. The thickness of the sheets was 2–6 nm, which corresponded to 2–4 unit cells of the c-axis of LaO 0.5 F 0.5 BiS 2 .
