    • نبذة مختصرة :
      A number of Ge₁₇Ga₄Sb₁₀S₆₉ˍₓSeₓ (x = 0, 15, 30, 45, 60, and 69) chalcogenide glasses have been synthesized by a melt-quenching method to investigate the effect of the Se content on thermo-mechanical and optical properties of these glasses. While it was found that the glass transition temperature (Tg) decreases from 261 to 174 °C with increasing Se contents, crystallization temperature (Tc) peak only be observed in glasses with Se content of x = 45. It was evident from the measurements of structural and physical properties that changes of the glass network bring an apparent impact on the glass properties. Also, the substitution of Se for S in Ge–Ga–Sb glasses can significantly improve the thermal stability against crystallization and broaden the infrared transmission region. ; This work was financially supported by the Natural Science Foundation of China (Grant Nos. 61435009 and 61377099) and sponsored by K.C.
