Abstract

Abstract A functional organic-inorganic composite amorphous material obtained by adding to an organic metal compound of silicon or germanium capable of being made amorphous by hydrolysis and dehydrating condensation, functional organic molecules soluble in a solvent capable of dissolving said organic metal compound, together with the solvent, followed by hydrolysis and dehydrating condensation to form an integrated composite.
