Problems solved by technology

[0011] However, due to the relatively high activity of zinc oxide, it is easy to chemically react with acidic substances or alkaline substances, and its mechanical strength is low, so the stability of the anti-reflection layer is relatively poor, and finally the service life of the anti-reflection layer is relatively short.

Abstract

Provided are an antireflection optical assembly and a manufacturing method thereof. The antireflection optical assembly comprises a substrate, an antireflection layer located on the surface of the substrate and a covering layer located on the surface of the antireflection layer, wherein the antireflection layer comprises a zinc oxide nanorod array composed of a plurality of zinc oxide nanorods, and the covering layer is made of one or more of silicon oxide, titanium oxide, aluminum oxide and zirconium oxide. The manufacturing method comprises providing the substrate, enabling the antireflection layer with a moth eye structure to be formed on the surface of the substrate, and enabling the covering layer to be formed on the surface of the antireflection layer, wherein the antireflection layer comprises a protrusion array composed of a plurality of protrusions, and the covering layer is made of one or more of silicon oxide, titanium oxide, aluminum oxide and zirconium oxide.

Description

technical field [0001] The invention relates to the technical field of nanomaterials, in particular to an anti-reflection optical component and a manufacturing method. Background technique [0002] When light is propagating, a part of the interface between different media usually changes its propagation direction and returns to the original medium, which is called light reflection. In general, the greater the difference in refractive index between different media, the more strongly light will be reflected at that interface. In the fields of photovoltaic devices and displays, how to reduce the reflection of light has always been a research hotspot. [0003] The compound eyes of moths can be viewed as an array of hexagonal nanostructure protrusions. The array is thought of as a homogeneous transparent layer on the corneal surface, with each nanostructured bump acting as an antireflection unit. This structure makes the moth's compound eyes less reflective, making them appear...
