From: Photoluminescence as a probe of phosphorene properties
Visual representation of a phosphorene nanosheet marked with armchair and zigzag directions; single phosphorene zigzag (b) and armchair (c) nanoribbon; d, e zigzag and armchair phosphorene nanotube, respectively, and f phosphorene quantum dots. The energy bandgap structure of g isolated phosphorene nanosheet. The figure was reproduced with permission from ref. 165. h Phosphorene zigzag and armchair nanoribbons. The figure was reproduced with permission from ref. 116. i phosphorene armchair nanotube. The figure was reproduced with permission from ref. 120. j Energy levels of zigzag triangular phosphorene quantum dots. The figure was reproduced with permission from ref. 166.
