Since the year 2014, when scientists first obtained black phosphorus using a sticky tape to peel the layers off, it has attracted tremendous interest as a novel two-dimensional material. After it was successfully produced, its outstanding optical properties have been unveiled. Various applications based on these properties have been reported. This study mainly reviews the unique optical properties and potential applications of black phosphorus. The optical performances of black phosphorus mainly include linear optical properties and nonlinear optical properties. Some examples include the anisotropic optical response, saturable absorption effect and Kerr effect. The researchers found that the nonlinear saturable absorption coefficients of black phosphorus are better than that of MoS and WS from the visible region to the near-infrared region. Compared with graphene, black phosphorus has a better nonlinear saturable absorption performance. After passivation or surface modification, black phosphorus is stable when exposed to oxygen and water. Herein, black phosphorus has the potential to be used in detector/sensors, solar energy harvesting, photocatalysts, optical saturable absorbers in ultrafast lasers, all optical switches, optical modulation, nanomedicine and some others in the near future.
自2014年科学家首次使用胶带从块状材料上剥离出黑磷以来，它作为一种新型二维材料引起了极大的关注。成功制备后，其出色的光学性能被揭示出来。基于这些性能的各种应用也已被报道。本研究主要综述了黑磷独特的光学性能和潜在应用。黑磷的光学性能主要包括线性光学性能和非线性光学性能。例如各向异性光学响应、饱和吸收效应和克尔效应。研究人员发现，从可见光区域到近红外区域，黑磷的非线性饱和吸收系数优于二硫化钼和二硫化钨。与石墨烯相比，黑磷具有更好的非线性饱和吸收性能。经过钝化或表面改性后，黑磷在暴露于氧气和水时是稳定的。在此，黑磷在不久的将来有潜力应用于探测器/传感器、太阳能收集、光催化剂、超快激光器中的光学饱和吸收体、全光开关、光调制、纳米医学等领域。
