Abstract

The outlines of present talk are photoinduced effects in light sensitive binary chalcogenides and refractory oxides reviewed on applying the concept for synthesis of composite materials. Generation of various nanostructured phases in the light absorbing media under specific irradiation conditions is exemplified by the formation of nanoparticles(voids)/matrix, nanocrystallite/amorphous and multi component composites. Evolution of a great variety phase compositions and morphologies and related properties which are not possible to realize with the unirradiated materials are demonstrated. The singnificance of the approach for the development of novel functional materials is discussed. The importance of knowledge on the fundamentals of the photographic process in classical silver halide materials for the proposed concept is emphasized..
