Thin films, the chemical processing up to gelation, the stoichiometry can be controlled very exactly and composites can include glass—ceramic, ceramic—ceramic and ceramic—organic compositions. Especially, the composites open a field of coatings which is difficult to achieve by other than sol-gel techniques. The exploitation of the potential will be an interesting future task.

Aqueous chemistry of metal cations: Hydrolysis, condensation and complexation,agram. They can lead either to small solute condensed species (polyanions or polycations) or to the formation of an infinite network (colloids, gels, or precipitates). Complexation by anionic species is finally discussed in the frame of an electronegativity-pH diagram. It also plays an important role during the formation of solid phases.

Optical properties of colorants or luminescent species in sol-gel glasses,nt of alkylsilicon alkoxides, or a precursor containing reactive glycidyl-oxopropyl substituents) can dissolve (otherwise almost insoluble) perylimide dyes, which are exceedingly photostable, and used in tunable lasers in the visible.
