Vitreous As2S3 and AsSe films are prepared by the spin-coating techniq
ue from solutions of corresponding chalcogenide glasses in amines. The
following photoinduced optical phenomena in the films are revealed an
d investigated: photodarkening, photoinduced linear dichroism, photodi
ffusion of silver and polarized photodoping. The photoinduced processe
s in the spin-coated films are compared with those observed in evapora
ted films of the same composition.
