Investigations of porous oxides as an antireflective coating for glass surfaces
Abstract
The paper examines applications of porous oxide films as an antireflective coating for glass surfaces. A porous aluminum oxide is deposited on glass surfaces from a clear organometallic derived sol; the index of the oxide coating is reduced by the presence of pores whose size is under 100 A, constituting up to 64% porosity. These pores do not interfere with the optical transparency of the material but reduce the index of refraction; thus they make it possible to obtain transparent oxide materials and coatings with very low index.
