New composite and nanocomposite materials consisting from amorphous chalcogenide (As2S3, As2Se3) and polymers such as polyvinylalcool (PVA) and polyvinylpyrrolidone (PVP) were prepared by inexpensive and easy coating technique from chemical solution and were investigated. Composite retains many properties of the initial components from which they are prepared. Morphology and optical properties of deposited materials in the form of films are presented. The decreasing of the As2S3 component in the composite leads to the shift of the absorption edge to higher energies and spheroid dimensions are decreased. For the samples As2S3:Pr3+/PVA an increasing of transparency in the visible region with respect to pure As2S3 was observed. As a result of ultraviolet light irradiation of the composites change of optical properties is observed. For example the refractive index may be change in value 0,1. This allows utilizing these structures for holographic recording of diffraction gratings. The investigated new composites are perspective for different photonic devices as well as for recording media with high resolution.
