The Sb(33)S(67) amorphous films were prepared by standard spin-coating technique. Prepared films were stabilized in a vacuum and then annealed in inert argon atmosphere. Silver film was deposited on top of Sb(33)S(67) film by vacuum thermal evaporation technique. The technique of step-by-step optically-induced diffusion and dissolution of Ag in Sb(33)S(67) amorphous films has allowed to design films with exact silver concentration. The host Sb(33)S(67) films were photodoped by dissolution of thin (~10 nm) film of silver, which resulted in amorphous films of good optical quality. We have analyzed affect of silver doping in the host materials on their composition, thickness, optical and thermal properties, their structure. Application of such films has been tested. The holographic gratings and optically-induced crystallized spots perspective for optical memories have been produced.
