Recently, a new type of phosphorus allotrope two-dimensional violet phosphorus (VP) has attracted widespread attention due to its excellent electronic, optical, and magnetic properties. Adjustable, large direct bandgap, high carrier mobility, and large light absorption make it a potential candidate for realizing optoelectronic applications. VP exhibits unique electronic structure, chemical stability, strong photo material interactions, and thermal stability, making it suitable for assembling intelligent optoelectronic devices. This review article comprehensively investigates the latest synthetic techniques used for developing VP, including its structural characteristics, stability, and degradation mechanism. In addition, this review presents various applications of VP in optoelectronics, including photodetectors, polarization detection, imaging systems, neuromorphic optoelectronic devices, etc. Finally, the challenges and future research directions of VP related to optoelectronics were discussed. Overall, as introduced, this review extensively investigates VP, covering its synthesis, structural insight mechanisms, and applications in optoelectronics, with the aim of promoting further research and development in this constantly evolving field.
