Abstract

The invention discloses a water chestnut type high-magnesium-content Zn<1-x>Mg<x>O nanometer structure and a preparation method of the water chestnut type high-magnesium-content Zn<1-x>Mg<x>O nanometer structure. A thermal evaporation method is adopted for the preparation method. A two-temperature-zone tube furnace is adopted for the thermal evaporation method. According to the process, pure zinc powder and pure magnesium powder which have a certain stoichiometric ratio are ground and mixed to serve as source material, a certain amount of the mixture is poured into a quartz boat, the quartz boat is placed in the bottom of a quartz tube, a substrate is placed on the opening of the quartz tube, and finally the quartz tube is placed in the tube furnace to allow the mixture to be heated and react under high-purity oxygen and inert gas, so that the water chestnut type high-magnesium-content Zn<1-x>Mg<x>O nanometer structure is obtained. The operation process is simple, the temperature of the source material region and the temperature of the substrate region are independently controlled, process parameters can be flexibly controlled, and nanometer material in the new form can be easily formed. The water chestnut type high-magnesium-content Zn<1-x>Mg<x>O nanometer structure and the preparation method solve the technical problem that phase separation easily happens to Zn<1-x>Mg<x>O nanometer alloy when the content of Mg exceeds 33%, the content of Mg in the Zn<1-x>Mg<x>O three-element alloy obtained through synthesis ranges form 77% to 97%, the Zn<1-x>Mg<x>O three-element alloy is of a water chestnut type nanometer structure, and possibility is provided for ZnMgO-based solar-blind region ultraviolet detector development.

Description

technical field [0001] The invention belongs to the technical field of preparation of nano functional materials, in particular to Zn with high magnesium content 1-x Mg x O nanostructures and methods for their preparation. Background technique [0002] As a semiconductor material with direct band gap and wide band gap, ZnO has a band gap of 3.37eV at room temperature and has excellent photoelectric properties in the ultraviolet region. Strong membrane and good stability. After incorporation of the Mg component, the formation of Zn 1-x Mg x O ternary alloy semiconductor, theoretically, the bandgap width can be continuously adjusted between 3.3-7.8eV, and the wavelength range corresponding to the bandgap width change is 368-159nm, and its absorption edge in the ultraviolet region increases with the increase of Mg content. Blue shift to short wavelength direction, theoretically when Zn 1-x Mg x When the Mg content in the O ternary alloy exceeds 65%, the Zn 1-x Mg x The ...
