The optical transmissions spectra of amorphous Ge-S-Se films of chemical
compositions (GeS₂)₅₀(GeSe₂)₅₀ and (GeS₃)₅₀(GeSe₃)₅₀, prepared by thermal evaporation,
have been measured over the whole 400 to 800 nm spectral range. It has been ascertained
that annealing of the films leads to the absorption edge shift into the short-wave spectral
region. The values of pseudo-gap width Eg and film refraction index n have been
determined. Changes in optical properties of films are caused by structural
transformations taking place in them under laser illumination and annealing.
