This paper presents the results of investigations of the manifestations of photostimulated structural changes in thermally deposited layers of As2Se3 from the absorption spectra in the far-IR region, using the methods of Fourier spectroscopy. It is shown that photostructural changes in the layers used for fabricating the holograms show up in an intensity redistribution of the bands of the IR absorption spectrum associated with the valence vibrations in moleculelike pyramidal structures that… CONTINUE READING
