Embodiment 1

[0025] (1) Sapphire cleaning

[0026] The sapphire used is double-polished sapphire with (0001) crystal face purchased on the market, with a thickness of 0.45 mm and a size of 1 cm*1 cm. Put the sapphire chip in deionized water, acetone and absolute ethanol for 20 minutes, respectively, to remove organic impurities on the surface; then wash it with deionized water, and finally put the sapphire substrate in absolute ethanol for later use.

[0027] (2) Cleaning of drainage sheet

[0028] The drainage sheet used is a common glass slide. Put the slides in deionized water, acetone and absolute ethanol in order to ultrasonically clean them for 20 minutes to remove organic impurities on the surface; then wash them with deionized water, and finally put the slides in absolute ethanol for later use.

[0029] (3) Monolayer SiO 2 Preparation of nanospheres

[0030] Purchased SiO with a diameter of 600nm 2 The nanospheres are soaked in absolute ethanol and stored with a density of 0.1...

Embodiment 2

[0033] This embodiment is similar to Embodiment 1, except that the pulling speed in step (3) is 130 μm / min. The prepared SiO 2 The nanosphere arrays are loosely arranged.

Embodiment 3

[0035] The present embodiment is similar to embodiment 1, and the difference is: in step (3) SiO 2 The original solution of nanosphere absolute ethanol and absolute ethanol were remixed at a ratio of 1:3. Use a pipette to pipette the reconstituted SiO 2 -The absolute ethanol solution is added dropwise on the drainage piece, and it is slowly flowed to the water surface, and the SiO2 in the prepared lifting solution is 2 The nanospheres condense into lumps and spread unevenly, and the Al 2 o 3 The substrate is immersed in the pulling liquid, and is pulled out of the liquid surface vertically and slowly. After the pulling is completed, the Al 2 o 3 multilayer SiO 2 nanospheres.

Abstract

The invention discloses a preparation method of a single-layer ordered silicon dioxide nanosphere array. The preparation method comprises the following steps of sapphire substrate cleaning; drainage sheet cleaning; single-layer SiO2 nanosphere preparing, wherein a drainage sheet is taken out and obliquely inserted into a certain amount of deionized water, a newly-prepared SiO2-absolute ethyl alcohol solution is dropwise added to the drainage sheet to form a single-layer SiO2 array, then a lifting solution is prepared, after standing is conducted till the liquid level is stable, a Al2O3 substrate is lifted through a coating lifting machine, standing is conducted till the Al2O3 substrate is dried, and then the single-layer SiO2 nanosphere array is formed on the Al2O3 substrate. According to the method, the single-layer ordered silicon dioxide nanosphere array is prepared through a draining, dispersing and lifting method at room temperature, and the prepared SiO2 nanosphere array is single in layer and compact in arrangement, can serve as a mask plate for the following process to prepare the large-area periodic and ordered nanoparticle array and prepare and research biological chips, optical devices and nanometer devices and is short in needed cycle and low in cost.
