Abstract

The invention provides metal ion modified black phosphorus as well as a preparation method and an application of the metal ion modified black phosphorus. The preparation method comprises the following steps of placing black phosphorus raw materials in a metal ion organic solution, performing impregnating under the temperature of 0-50 DEG C for 5min to 2h, and then performing blow-drying under protective gas so as to prepare the metal ion modified black phosphorus. The invention further provides the metal ion modified black phosphorus prepared by the preparation method, and the application of the metal ion modified black phosphorus in thin-film transistor materials, battery negative electrode materials, flexible display materials, light emitting diode materials, optical switch materials and biosensor materials. The metal ion modified black phosphorus provided by the invention can utilize the metal ions to improve the structural stability and the property stability of the black phosphorus in the existence of water and oxygen gas under the condition of being not changing the intrinsic attributes of the black phosphorus, so that the antioxidant ability of the black phosphorus is improved.

Description

technical field [0001] The invention belongs to the technical field of two-dimensional black phosphorus, and in particular relates to a metal ion-modified black phosphorus and a preparation method and application thereof. Background technique [0002] In 2014, the family of two-dimensional materials ushered in a new member—black phosphorus, which has a two-dimensional unit layer structure similar to graphene, and each phosphorus atom in the layer is covalently bonded to three adjacent phosphorus atoms. Connected to form a folded honeycomb structure, and the layers are connected by van der Waals force. However, unlike graphene, black phosphorus is a natural semiconductor with adjustable bandgap width and superior electrical properties. It is considered to be able to solve the problems that graphene cannot solve as a conductor. It is expected to replace silicon and become the semiconductor industry. core material. Compared with other semiconductors, the optical properties of...
