The sol-gel method was widely used in the preparation of photonic materials and structures during the last decades. The design and preparation of hybrid nanocomposites for photonics are widely described in Refs [7,145-147]. The wide range of photonic structures prepared using the sol-gel method include colloidal crystals based on silica or polystyrene spherical particles [148,149], photonic crystals [150-152], photonic bandgap materials [153-155], and opals based on the deposition of silica, titania, and/or ceria in the voids of an ordered array of PMMA spheres [156]. A more extensive overview of photonic materials by sol-gel method can be found in Chapter 28.
