Abstract

Inorganic multilayered optical systems are produced by applying to a glass substrate a flowable composition containing nanoscale solid inorganic particles containing polymerizable or polycondensable organic surface groups, polymerizing and/or polycondensing those surface groups to form an organically crosslinked layer, applying to the organically crosslinked layer and polymerizing/polycondensing a flowable composition producing a different refractive index from the first layer (optionally repeated one or more times), and one-step thermal densifying and removing the organic components. The systems so produced are suitable as interference filters and antireflection systems.
