Description
Summary:The liquid phase exfoliation (LPE) of layered black phosphorus (BP) material is essential in the field of electronics. N -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. This work presented a cost-effective and simple route for the fabrication of high-quality and large lateral-size black phosphorus nanoparticles/nanosheets by liquid-phase exfoliation.
