Phosphorene: From Black Phosphorus to Phosphorene: Basic Solvent Exfoliation, Evolution of Raman Scattering, and Applications to Ultrafast Photonics (Adv. Funct. Mater. 45/2015)

Abstract

On page 6996, H. Zhang, X.-F. Yu, and co-workers describe a simple liquid exfoliation method for production of phosphorene with excellent water stability, controllable size and layer number, as well as high yield. The resulting 1?4-layered phosphorene exhibits layer-dependent Raman scattering characteristics, which provide a fast and efficient means for in situ determination of the layer number of phosphorene.
