以一氧化铅粉末和氢碘酸为试剂，在十二胺的辅助下制备了单晶 PbI2 纳米带束。组装好的 PbI2 纳米带束可以通过长时间的超声处理分散成纳米带。所制备的纳米带束由数条纳米带组成，纳米带的长度为数十微米，宽度为50-150纳米，厚度约为100纳米。 20纳米。 X射线衍射（XRD）、扫描电子显微镜（SEM）、场发射扫描电子显微镜（FE-SEM）、透射电子显微镜（TEM）、电子衍射（ED）和高分辨率透射显微镜（HRTEM）用于表征所制备的产品。初步提出了PbI2纳米带束可能的形成机制。
Single-crystalline PbI2 nanobelt bundles have been prepared using lead monoxide powder and hydroiodic acid as reagents at the assistance of dodecylamine. The assembled PbI2 nanobelt bundles can be spilt into nanobelts through long-playing sonication. The prepared nanobelt bundles consist of several nanobelts and the nanobelts have lengths of tens of microns, widths of 50-150 nanometers, and thicknesses ca. 20 nanometers. X-Ray diffraction (XRD), scanning electron microscopy (SEM), field emission scanning electron microscopy (FE-SEM) transmission electron microscopy (TEM), electronic diffraction (ED), and high-resolution transmission microscopy (HRTEM) was used to characterize the as-prepared product. The possible formation mechanism of PbI2 nanobelt bundles was tentatively proposed.
