摘要：

The study investigated the anti-reflective properties of metal-coated nanopillar arrays with high-aspect ratio. Aluminium oxyhydroxide nanopillar arrays were prepared by using aluminium anodic oxidation, hydrothermal synthesis, and platinum sputtering on their surface. The anti-reflective properties were evaluated on four types of nanostructures such as nanolens and nanopillar arrays with aspect ratios of 1:0.5, 1:3, 1:9, and 1:14. The nanopillar arrays with an aspect ratio of 1:14 demonstrated extremely low reflectance <0.18% at 550 nm wavelength of all measured incident angles.
