Recent results concerning fabrication and optical features of the metal- and semiconductornanoparticles doped sol-gel are reviewed. The nanoparticles of copper, copper oxides, sulfides and selenides have been produced by means of the modified silica-based sol-gel technique within the two types of materials: amorphous silica films and monolithic glasses. The features of the optical absorption are discussed in dependence on the chemical composition. Optical properties are varied with element composition of the compounds, size of particles, their concentration, etc. The quantum confinement and partial surface chemical modification of the nanoparticles are considered as possible reasons for appearance of optical features at the copper multivalent compounds.
