Abstract

The invention discloses a bell-shaped ZnO nanometer device material and a preparation method thereof. A new product is added for ZnO nanometer structural materials, and gaps of the prior art at home and abroad are filled. Soluble zinc salt, deionized water and hexamethylene tetramine are adopted as raw materials of the bell-shaped ZnO nanometer device material and mixed and dissolved to generate the bell-shaped ZnO nanometer device material by a one-step ultrasonic irradiation process, the bell-shaped ZnO nanometer device material is bell-shaped, a nanometer tube and a nanometer bar are automatically assembled to form the bell-shaped ZnO nanometer device material, the basic structure of the nanometer tube (a bell cover) is a six-prism-shaped tube, a tube opening of the nanometer tube is hexagonal, deformation shapes include a triangle and a diamond, and the nanometer bar (a bell tongue) is cylindrical. The bell-shaped nanometer structure is better in scattering property, two bells are connected locally to form a coaxial cable structure, and a plurality of bells are gathered together to form a trumpet-flower structure. The bell-shaped ZnO nanometer device material is novel in structure and can be applied to fields of medical antibiosis, photoelectric devices, gas sensors, solar batteries and the like.
