METHOD FOR PRODUCING HYDROGENATED AMORPHOUS SILICON-CONTAINING COLLOIDS AND/OR COMPOSITE COLLOIDS AND FOR ENCAPSULATING SUBSTANCES WITH HYDROGENATED AMORPHOUS SILICON-CONTAINING COMPOSITE COLLOIDS, HYDROGENATED AMORPHOUS SILICON-CONTAINING COLLOIDS AND/OR COMPOSITE COLLOIDS, SUBSTANCES ENCAPSULATED WITH SILICON-CONTAINING COMPOSITE LAYERS, AND USE THEREOF

摘要

Hydrogenated amorphous silicon-containing colloids or composite colloids have a silicon-containing shell which surrounds the hollow colloids or composite colloids. The colloids have a spherical geometry. The silicon-containing composite colloids have a spherical geometry and a diameter of between 2 nm and 7 nm in scanning electron micrographs, and the silicon-containing colloids have a spherical geometry with a cavity and a diameter of between 50 and 200 nm in scanning transmission electron micrographs. The cavity is surrounded by a shell with a thickness of between 3 and 10 nm.
