In-situ growth of perovskite nanocrystalline particles on a two-dimensional black phosphorus surface
Recently, researcher Yu Xuefeng of the Institute of Advanced Technology of the Chinese Academy of Sciences in Shenzhen and collaborator Li Jia have made new advances in the research field of perovskite/black-phosphorus composite nanomaterials and successfully grown in situ on black phosphorus nanoplates through a simple liquid-phase preparation process. All-inorganic perovskite nanocrystalline particles produced low-dimensional heterojunction structures of zero-dimensional perovskite/two-dimensional black phosphorus, exhibiting excellent potential for photovoltaic applications. Related Results In situ growth of all-inorganic perovskite nanocrystals on The black phosphorus nanosheets are published in the international journal Chemical Communications. The first author of the paper is assistant researcher Huang Hao.
Zero-dimensional (0D) nanocrystals or quantum dots are distributed on the surface of two-dimensional (2D) materials. The composition of low-dimensional composite systems has attracted the attention of researchers in recent years. This structure can provide more degrees of freedom to design various The quantum system, by combining the unique advantages of the zero-dimensional and two-dimensional materials, exerts a synergistic effect, and provides new opportunities for the realization of high-performance optoelectronic applications. The 2D black phosphorus and 0D perovskites have their own excellent optoelectronic properties and combine the two. It will certainly provide great support for the exploration of basic principles of optoelectronics and the application of high-performance optoelectronic devices, but relevant studies have not yet been reported.
In this work, researchers designed and built a new 0D-2D low-dimensional composite material system. Using a simple liquid-phase preparation process, it successfully realized the original inorganic perovskite nanocrystals directly on the black phosphor nanosheets. The high-dimensional low-dimensional composite material with uniform structure, controllable morphology, and excellent photoelectricity is obtained. This composite material combines the superior electrical properties of black phosphorus with the unique optical properties of perovskite nanocrystals or quantum dot materials. Combine with each other to provide a new material system for the realization of high-performance optoelectronic devices.
