The liquid phase exfoliation (LPE) of layered black phosphorus (BP) material is essential in the field of electronics. -Methyl-2-pyrrolidone (NMP) is one of the most promising precursors for obtaining BP nanosheets/nanoparticles, but the longer sonication time leads to smaller production of phosphorene. Herein, for the first time, the large lateral size fabrication of phosphorene was attained through NMP solvent by optimizing the process parameters. The resultant dispersions were characterized by atomic force microscopy, X-ray powder diffraction, Raman spectroscopy, scanning electron microscopy, transmission electron microscopy, and ultraviolet-visible spectroscopy. The characterization results revealed that the average lateral sizes of BP nanoparticles were found to be 67.8 ± 18.6 nm and the lateral size of fabricated BP nanosheets was found to be 5.37 μm. Moreover, this research provides a strategic approach for the mass production of phosphorene for photodetection applications.
层状黑磷（BP）材料的液相剥离（LPE）在电子领域至关重要。N-甲基-2-吡咯烷酮（NMP）是获得BP纳米片/纳米颗粒最有前景的前驱体之一，但较长的超声处理时间会导致磷烯产量降低。在此，首次通过优化工艺参数，利用NMP溶剂实现了大横向尺寸磷烯的制备。通过原子力显微镜、X射线粉末衍射、拉曼光谱、扫描电子显微镜、透射电子显微镜和紫外可见光谱对所得分散体进行了表征。表征结果表明，BP纳米颗粒的平均横向尺寸为67.8±18.6 nm，制备的BP纳米片的横向尺寸为5.37μm。此外，本研究为用于光检测应用的磷烯大规模生产提供了一种策略性方法。
