Physical ageing induced by above-bandgap photoexposure is studied in As–Se glasses using the differential scanning calorimetry technique. The kinetics of this effect are compared with those caused by natural storage in the dark. Acceleration of physical ageing processes is recorded for Se-rich glasses having more than three Se atoms in their chains.
