Abstract

The invention discloses tetrahedral zinc oxide single-crystal particles and a preparation method thereof. The preparation method comprises the steps that anhydrous zinc acetate and octanol are mixed and are stirred evenly, a mixture of an ethyl alcohol stearate solution and lauryl amine is added into the mixture, and even mixing and stirring are performed to obtain a transparent solution. The transparent solution is heated to 140-145 DEG C under gas protection, and reflux reaction is performed at the temperature; after reaction is completed, centrifugal separation and washing are performed to obtain the tetrahedral zinc oxide single-crystal particles. The method is simple and easy in technological process, the reaction time is shorter, the obtained product has tetrahedral morphology, is simple in morphology and controllable in size, has the good application prospect in the fields of new energy resources and sensing and can also serve as an additive for high-end sunscreen skin care products.

Description

technical field [0001] The invention relates to a tetrahedral zinc oxide single crystal particle and a preparation method of the tetrahedral zinc oxide single crystal particle, belonging to the technical field of semiconductor preparation. Background technique [0002] Zinc oxide is a wide bandgap n-type semiconductor material, and nano-zinc oxide has unique properties that bulk materials do not have. These special effects make nano zinc oxide have good application prospects in optics, electricity, magnetism, thermodynamics and so on. In particular, nano-zinc oxide has unique photoelectric properties, anti-ultraviolet radiation and antibacterial properties, making it an important research object in many fields such as chemical industry, biomedicine, and cosmetics manufacturing. [0003] Zinc oxide with different microscopic morphology can endow products with better performance. The morphology of zinc oxide disclosed at present has various shapes such as rod shape, flake sha...
