Abstract
A phase-transition type vanadium oxide material and a preparation method therefor. The preparation method includes the following steps: providing a vanadium oxide base material, and implanting gaseous ions into the vanadium oxide base material, to obtain a phase-transition type vanadium oxide material having a preset phase-transition temperature. Subsequently, optionally, further annealing may be performed to adjust a bubble generation status in vanadium oxide after the gaseous ions are implanted, to further adjust the stress and strain and the phase-transition temperature. The method for preparing a phase-transition type vanadium oxide material consistent with the present invention has simple steps, desirable process reproducibility, high flexibility, and the phase-transition temperature of vanadium oxide can be continuously adjusted by changing an implantation dosage of the gaseous ions. In addition, the present invention has desirable compatibility, and can be combined with other phase-transition temperature methods, to achieve a larger phase-transition temperature adjustment range.
