Abstract

The invention discloses a method for preparing a vanadium oxide nanoparticle array by rapid heat treatment. The method comprises the following steps: (1) cleaning an aluminum oxide substrate and a glass slide; (2) lifting a single-layer silica nano ball, evenly arranging a layer of silica nanospheres on the aluminum oxide substrate by adopting a dip coating method; (3) magnetron sputtering of a vanadium metal film: by taking vanadium metal as a target, depositing a layer of vanadium metal film on the overall aluminum oxide substrate in the step (2) by adopting a target magnetron sputtering method; (4) carrying out rapid heat treatment to form a vanadium dioxide film. The particle sizes of the array prepared by the method are at nanometer level, ordered in arrangement height, simple in preparation method, and fewer in controlled technological conditions, and spherical and triangular vanadium oxide nanoparticle arrays can be prepared by adjusting experiment parameters under the same experiment steps, so as to greatly shorten the experimental period in preparation.

Description

technical field [0001] The invention belongs to the technical field of semiconductors, and in particular relates to a method for preparing vanadium oxide nanoparticle arrays through rapid heat treatment. Background technique [0002] VO 2 A reversible phase transition from semiconductor to metal occurs at 68°C, and its structure changes from monoclinic at low temperature to tetragonal at high temperature. With the change of the structure, the resistivity, magnetic susceptibility, light transmittance and reflectivity of the material change suddenly, so it has a wide application prospect in the fields of optoelectronic devices and smart windows. [0003] As the basis of the development of nanotechnology, nanomaterials have unique properties such as photoelectricity, heat, and chemical activity, and have good development prospects in various fields, so more and more researchers have paid attention to them. With the improvement of the preparation process, VO 2 The size of the...
