摘要

Disclosed is a process of making a glass article containing a thin surface film antireflective coating made by providing a dispersion containing at least one metalloorganic compound in solution, depositing a thin coating of such dispersion on the glass substrate, heating the film to drive off the solvent and to decompose the organic components, thus forming a glass film from the remaining inorganic oxide components, further heating the glass film layer to cause phase separation thereof, and thereafter etching and leaching such film to dissolve out preferentially one of the phases of the phase-separated glass, leaving a skeletonized surface film having a graded refractive index; and products resulting from such process.
