Nanorods make "ideal" anti-reflection coatings Mar 1
Physicists in the US claim to have created the first thin optical film with a refractive index close to that of air. The film consists of an array of obliquely-deposited nanorods, which can collectively have a refractive index as low as 1.05. The physicists also claim several graded layers of the films can produce an optical coating that "virtually eliminates" reflection at all wavelengths (Nature Photonics).
