Research output: Contribution to journalArticlepeer-review


Photodarkening phenomena in the amorphous Se and Se95Te5 films at the μs light pulses irradiation are investigated. The process of photodarkening during each of the individual 1, 10 or 100 μs pulses and also the processes proceeding between successive pulses are recorded and analyzed. The darkened film was shown to restore initial optical properties after some stay in darkness without any additional irradiation or heating. Photodarkening is very strongly dependent on the light pulse fluence.
