It is shown that the photostructural changes introduced during irradiation of chaclogenide glasses are dependent on the glass structure and composition. Photodarkening experiments performed on a series of As-S-Se glass suggest that the photostructural changes decrease as the network connectivity tends to an average coordination value of <r>=2.4. Photorelaxation experiments perfomed on Ge-Se glasses show that contamination with oxygen does not appear to significantly affect photostrucral changes. On the contrary, the addition of CsCl in a Ge-Sb-S glass appears to suppress photostrucral effects entirely.
