Abstract

An ultralow refractive index is very advantageous when one designs antireflective coatings. We successfully obtained high-quality MgF 2 thin films with ultralow refractive indices from autoclaved sols prepared from magnesium acetate and hydrofluoric acid. The MgF 2 films consist of nanosized particles, and they have high laser-exposure durability at 193 nm . The reflectance of the antireflective coating with five layers, of which the top layer is formed by our method, is lower than 0.6% in the incident angle range of 0 °– 60 ° at 193 nm .
