摘要：

This work reports the effect of different modifiers (ZnO/WO3) on the thermal properties and mid-infrared emission of 2.7 mu m in Er3+-doped tellurite glasses. The Judd-Ofelt parameters, radiative transition probability, radiative lifetime and branching ratio of prepared samples are calculated and discussed. It is found that the present tungsten-modified tellurite glass doped with Er3+ possesses large calculated emission cross section around 2.7 mu m (2.03 x 10(-20) cm(2)). The advantageous spectroscopic characteristics as well as good thermal stability suggest that the present glasses have potential applications for 2.7 mu m laser materials. (C) 2013 Elsevier B.V.
