The advent of multilayer antimonene nanoribbons with room temperature orange light emission.

Multilayer antimonene nanoribbons with room temperature orange light emission uniformly distributed on InSb were synthesized by the plasma-assisted process. The bandgap opening was caused by the quantum confinement effect of the nanoribbon structure and the turbostratic stacking of antimonene layers. This attractive two-dimensional material, whose band structure is proper for applications of transistors and light-emitting diodes, was first synthesized. [ABSTRACT FROM AUTHOR]
