在常压条件下，以红磷代替白磷为前驱体，采用固液固一步反应法制备黑磷纳米带。通过扫描电镜研究，纳米带的厚度从微米到几十纳米不等。能量色散x射线能谱和x射线衍射分析表明，纳米带具有黑磷的组成和结构，透射电镜显示其呈典型的沿b轴堆积的层状结构，扫描透射电镜结合能量色散x射线能谱分析表明，黑磷结构中掺杂了铋。在环境条件下，扫描隧道显微镜可以直接测量纳米带。
Black phosphorus nanobelts are fabricated with a one-step solid-liquid-solid reaction method under ambient pressure, where red phosphorus is used as the precursor instead of white phosphorus. The thickness of the as-fabricated nanobelts ranges from micrometers to tens of nanometers as studied by scanning electron microscopy. Energy dispersive X-ray spectroscopy and X-ray diffraction indicate that the nanobelts have the composition and the structure of black phosphorus, transmission electron microscopy reveals a typical layered structure stacked along the b-axis, and scanning transmission electron microscopy with energy dispersive X-ray spectroscopy analysis demonstrates the doping of bismuth into the black phosphorus structure. The nanobelt can be directly measured in scanning tunneling microscopy in ambient conditions.
