GexS1−x glasses. II. Synthesis conditions and defect formation*

Electron paramagnetic resonance spectroscopy at 9 GHz and at sample temperatures of 77 and 300 K was applied to the investigation defect formation and its dependence on synthesis conditions for Ge x S 1− x glasses with 0.10 ≤ x ≤ 0.45. It is shown that the influence of synthesis conditions on defect formation in glasses depends on the type of intrinsic paramagnetic centers and the glass composition. New intrinsic paramagnetic centers are detected in glasses with 0.10 ≤ x ≤ 0.325. The attribution of two of these with g -values of 2.01 and 2.005 was proposed. It was shown that the influence of the synthesis conditions and γ-irradiation on the defect formation depends on both glass composition and the type of intrinsic paramagnetic center in each of three composition ranges in the glass-forming composition range.
