摘要：

We have studied the thermal stability, in terms of the glass transition and crystallization, of (GeS2)(75)(Ga2S3)(25) glasses doped with high amounts of Er2S3 (1.8 to 2.4 mol. %). These bulk glasses were synthesized from the sulphides of Ge, Ga and Er by conventional rapid quenching of the melts in ice-water. The Er3+ photoluminescence spectrum is a broad emission band at similar to 1540 nm. The PL lineshape does not show any dependence on the Er3+ content. The PL decay times are in the 1.13 - 1.55 ms range, and decrease with the rare earth content.
