Abstract LaO0.5F0.5BiS2 nanosheets were produced by ultrasonification. A slightly reddish colloidal suspension was obtained by ultrasonification of LaO0.5F0.5BiS2 powder 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.

超声合成LaO 0.5 F 0.5 BiS 2 纳米片

摘要 LaO0.5F0.5BiS2 纳米片是通过超声波制备的。通过在乙醇中超声处理 LaO0.5F0.5BiS2 粉末获得略带红色的胶体悬浮液。干燥悬浮液的透射电子显微镜 (TEM) 图像表明 LaO0.5F0.5BiS2 的纳米片形貌,电子衍射斑点表明具有 4 倍对称性。薄片的厚度为 2-6 nm,对应于 LaO0.5F0.5BiS2 的 c 轴的 2-4 个晶胞。
