摘要：Gamma-ray (gamma-ray) sensitivity has been studied in Ag-doped and/or AgI-modified Ge-Ga-S glasses. The sensitivity is controllable in terms of silver presence. Compared to the silver-free sample, the AgI-modified glass shows greater sensitivity to gamma-ray irradiation regarding larger change in the transmission spectra (Delta T), whereas improved resistance to gamma-ray irradiation occurs in the silver-doped AgI-modified glass with only 1 mol% silver metal being intentionally added.
