| description | The invention provides a black phosphorus/zinc oxide heterojunction material, a preparation method and application thereof, and a wearable anti-UVA skin protection device, and particularly relates to the technical field of flexible photoelectric sensors. The black phosphorus/zinc oxide heterojunction material provided by the invention comprises zinc oxide nano-microspheres grown on the surface of a flexible substrate and black phosphorus nanosheets coated on the surfaces of the zinc oxide nano-microspheres, the zinc oxide nanospheres are formed by centripetal clustering of zinc oxide nanosheets; the mass ratio of the black phosphorus nanosheets to the zinc oxide nanospheres is (0.4-0.5): 1; the loading capacity of the black phosphorus nanosheet on the flexible substrate is 7 to 10 mg/cm < 2 >. According to the invention, a stable chemical interface is constructed by utilizing the construction of the black phosphorus and zinc oxide heterojunction and a formed P-O-Zn bond, so that the surface defect passivation |
