The sol-gel process as a soft-chemistry route for glass and ceramics can be modified by incorporating organics and be used to fabricate inorganic-organic composite materials. One of the major problems related to this type of processing is the control of phase size of the inorganic and the organic part. Therefore, it is necessary to provide links between inorganic and organic units. Phase size of the inorganic components can be controlled by growth controlling additives (GCA) which can be used to stabilize inorganic particles in the nano range. If these additives are bifunctional, for example, carrying hydrolyzable silanes or polymerizable groups, the modified particles can be used as precursors for further processing like sol-gel precursors or organic monomers. Using these conceptions, it is possible to process ceramic polymer, semiconductor polymer or even metal polymer composites with phase dimensions in the lower nano range to be used for optical purposes. In the paper, the basic conception, synthesis chemistry and examples for application will be given.
