We present insightful results on the kinetics of photodarkening (PD) in GexAs45-xSe55 glasses at the ambient and liquid helium temperatures when the network rigidity is increased by varying x from 0 to 16. We observe a many fold change in PD and its kinetics with decreasing network flexibility and temperature. Moreover, temporal evolution of PD shows a dramatic change with increasing x.

Transmission spectra of GexAs45-xSe55 thin films with x = 0, 5 and 16, before and after illumination with 532 nm laser light at room and liquid He temperatures. The intensity of illumination was kept at 1W/cm2 for all samples at both the temperatures.
Variation of absorption coefficient with time for the wavelength, which has an initial transmittance of 0. 3 before illumination. Hollow circles represent the experimental data and the red line indicating the theoretical fit using Eq. 2.
