| Functionalized colloidal nanoparticles of polymers and inorganic oxides have been utilized to fabricate periodic stacked dielectric layers. Ionic absorption of colloidal polymeric particles followed by a post-assembly chemical processing allows fabrication of a large area (2x2cm) transparent polymeric dielectric Bragg grating. The period of the Bragg gratings can be tuned from less than 100 nm up to a few hundred nanometers. Other inorganic colloidal nanoparticles, such as TiO2, ZnO, and SiO2, have been incorporated into nanostructured layers and their properties have been investigated. |
