摘要

Antireflection (AR) coalings arc indispensable require-mcnls for many optical applications such as flat-panel dis-plays, solar cells, lasers, and other optoelectronic devices. Two approaches are available as model methods for achieving low surface reflectivity: 1) Fabrication of nanoporous layers using a particle coating, phase separation of a binary polymer blend, and polyelectrolyte multilayer coating. These thin dielectric films with a low refractive index can improve light transmission via the destructive interference of the reflected light at the air-film and the film-substrate interfaces; 2) Fabrication of surface relief structures using holographic lithography, reactive-ion etching, and plate embossing. The array of conical protuberances having sinusoidal profiles cause variations in the refractive index between the air and substrate to be gradual, dramatically reducing the reflection losses at the surface.
