Vitreous As2S3 and AsSe films are prepared by the spin-coating technique from solutions of corresponding chalcogenide glasses in amines. The following photoinduced optical phenomena in the films are revealed and investigated : photodarkening, photoinduced linear dichroism, photodiffusion of silver and polarized photodoping. The photoinduced processes in the spin-coated films are compared with those observed in evaporated films of the same composition.
