Bilayer Antireflective coatings with periodically arranged SiO 2 hierarchical nanostructures are fabricated on dense SiO 2 matrix base layer using glancing angle deposition technique (GLAD). The refractive indices of monolayer SiO 2 were tuned from 1.46 to 1.08 by changing the deposition angle (α) from 0° to 88°. The fabricated bilayer SiO 2 AR (BSAR) film possess high optical omnidirectional broadband transparency and tunability at a desired wavelength range showing <1 % reflectance. The current AR design is practically applicable on various supporting substrate materials (η varies from 1.45‐1.9). Further details can be found in the article 1700942 by Zhengjun Zhang and co‐workers.
