“…The optical changes caused by ion irradiation were very similar to the well-known photodarkening phenomenon in amorphous arsenic sulfide films [2,4]. The optical transmittivity of the films has decreased and the optical absorption edge has shifted to lower energies ( Fig.…”

“…A number of physical and especially optical properties of amorphous chalcogenide thin films and bulk glasses can be efficiently changed by exposing them to light, heat or ionizing irradiation [1 -7]. These effects have attracted a significant attention both of the basic [2,7] and applied research [8]. The largest interest was devoted to photo-induced changes of the optical band gap (photo-darkening or photobleaching), which was extended to the investigation of the volume and refractive index changes or even polarization effects in model-type As 2 S 3 , AsSe binary chalcogenides and a-Se.…”

The influence of H+ and D+ ion irradiation and laser illumination on the optical absorption edge, the refractive index and the Raman scattering spectra of as‐deposited and annealed As2S3 films have been investigated. It was established, that a significant similarity exists between optical changes induced in As2S3 films by light illumination and by irradiation with light ions and also between structural changes thought to be responsible for these effects.The changes are connected with electron excitation processes in both cases and further initiation of atomic rearrangements within the amorphous phase.
