摘要

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 0.6percent in the incident angle range of 0 deg-60 deg at 193 nm.
