Embodiment Construction

[0101] The present invention will be further described below in conjunction with accompanying drawing:

[0102] figure 1 As shown, in order to quickly prepare the zinc oxide state diagram, the beaker should be firmly placed on the base, and three cone stoppers are set on the upper part of the beaker to fix the argon tube, magnetic stirrer, and adding funnel. The upper part of the beaker is filled with argon gas, and the lower part is Zinc chloride aqueous solution + sodium hydroxide aqueous solution + oleic acid + absolute alcohol mixed solution.

[0103] To operate in sequence, the position and steps are correct.

[0104] figure 2 As shown, it is the morphology diagram of the particle arrangement of the zinc oxide product, and the particles are neat, regular and clear.

[0105] image 3 , 4 As shown, it is the state diagram of zinc oxide single crystal particles, and the single crystal is petal-shaped, with the flower core opening radially outward.

Abstract

The invention relates to a rapid and simple preparation method of nano-zinc oxide, which takes zinc chloride and sodium hydroxide as raw materials, takes the sodium hydroxide as a strong alkaline regulator, takes oleic acid as a precipitant, takes anhydrous ethanol as a solvent and a centrifugal separating agent, takes deionized water as the solvent and a cleaning agent and takes argon as protective gas. The rapid and simple preparation method comprises the steps of firstly preparing zinc chloride and sodium hydroxide water solution, then mixing with the oleic acid and the anhydrous ethanol for forming solution, carrying out chemical reaction and grain growth under the state of 20 DEG C, carrying out high-speed centrifugal separation, washing and vacuum drying, and finally preparing the white, granular, petal-shaped and single crystal nano-zinc oxide. The preparation method is rapid and simple and can be completed within 4-5 hours without the need of heating, the product has regular and clear appearance, the diameter of single crystal is 2-4mu m, the thickness of single flake is 4-5nm, the chemical and physical performances are stable, the prepration cost is low, the yield can be as high as 92.5%, the product has high purity which can achieve 99.7%, so that the preparation method is the ideal rapid and simple preparation method of the nano-zinc oxide.

Description

technical field [0001] The invention relates to a quick and simple preparation method of nanometer zinc oxide, which belongs to the technical field of preparation methods and applications of inorganic semiconductor light-emitting materials. Background technique [0002] Zinc oxide, commonly known as zinc white, belongs to hexagonal wurtzite structure, its appearance is white or light yellow crystal or powder, non-toxic, odorless, amphoteric oxide, insoluble in water and ethanol, soluble in strong acid And strong alkali, easy to absorb carbon dioxide and water in the air, especially active zinc oxide. [0003] Zinc oxide is a wide-bandgap semiconductor luminescent material, which can produce ultraviolet light with a wavelength of 370-400nm after being excited by photons and electrons, as well as visible light with different wavelengths of blue, green and yellow, so it has a wide application prospect in the field of luminescence. [0004] Nano-zinc oxide is a kind of high-pur...
