Example Embodiment

[0030] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0031] The raw materials used in the present invention are all commercially available materials, and the preparation method includes the following steps:

[0032] (1) Cleaning of sapphire substrate:

[0033] The sapphire used is a double-polished sapphire substrate with (001) crystal face, with a thickness of 0.45 mm. Put the sapphire chip into deionized water, acetone and absolute ethanol for 20 minutes ultrasonic cleaning to remove the organic impurities on the surface; then rinse with deionized water, and finally put the sapphire substrate in absolute ethanol for use.

[0034] (2) Preparation of monodisperse SiO 2 Mask layer:

[0035] First, insert the cleaned glass slide obliquely into a certain amount of deionized water, and then use a pipette to remove the 600nm SiO 2 -Anhydrous ethanol solution is dripped onto the drainage sheet and allowed to flow slowly onto t

Abstract

The invention discloses a preparation method of a gold triangular nanoparticle array and vanadium dioxide film composite embedded structure. The preparation method comprises six steps of cleaning of a sapphire substrate, preparation of a monodispersion SiO2 mask layer, preparation of a gold triangular nanoparticle array structure, preparation of a vanadium film, preparation of a vanadium dioxide film and preparation of a gold reflection layer. The prepared film consists of the gold triangular nanoparticle array, the vanadium dioxide film and the gold reflection layer; and through adjustment of the preparation sequence, the gold triangular nanoparticle array can be embedded in the vanadium dioxide film to realize adjustment of resonant wavelengths. A film preparation absorber has such advantages as wider adjustment of visible light-near infrared band resonant wavelengths, high absorption efficiency, simple structure and small size, and can be applied to such aspects as light detection, electromagnetic switches and sensors.
