Paper Abstract

Transparent gels, either purely inorganic or organically modified, are obtained through a sol- gel process circumventing the usual hydrolysis-condensation path. This non-aqueous route, which may also be described as a `non-hydrolytic' process, results in gels containing low amounts of hydroxyls vis-a-vis conventional gels. The mechanical properties of the gels range from rubbery to hard according to the functionality of the precursor. Erbium-doped methylsilsesquioxane shows luminescence at 664 nm under pumping with an argon line at 488 nm. Pure SiCl4-derived gels show an additional emission, ascribed to the 4F7/2 yields 4I3/2 transition at 710 nm.
