采用超声法制备了LaO0.5F0.5BiS2纳米片。将LaO_（0.5）F_（0.5）BiS_2粉末在乙醇中超声处理，得到微红色的胶体悬浮液。透射电子显微镜（TEM）的干燥悬浮液的图像表明的纳米片形貌的LaO0.5F0.5BiS2，和电子衍射斑点表示4重对称。薄片的厚度为2-6 nm，这对应于LaO 0.5F 0.5BiS 2的c轴的2-4个晶胞。
LaO0.5F0.5BiS2nanosheets were produced by ultrasonification. A slightly reddish colloidal suspension was obtained by ultrasonification of LaO0.5F0.5BiS2powder in ethanol. Transmission electron microscope (TEM) images of the dried suspension indicated the nanosheet morphology of LaO0.5F0.5BiS2, 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 LaO0.5F0.5BiS2.
