摘要：

0.2 wt.% Dy3+-doped and 0.2 wt.% Dy3+, 0.5 wt.% Tm3+-codoped (100-x)GeS2 center dot xIn(2)S(3) (x = 5,10,15,20,25) chalcogenide glasses were prepared. Their spectroscopic properties were analyzed based on absorption (ranges from 500 to 3000 nm) and emission (ranges from 1000 to 4700 nm) measurements. The Judd-Ofelt strength parameters Omega(t) (t = 2, 4, 6) and the spectroscopy parameters A(rad), beta and T-rad were calculated, and the sigma(emi) of the 1330, 2930 and 4320 nm fluorescences were estimated. These Dy3+-doped and Dy3+, Tm3+-codoped Ge-In-S chalcogenide glasses are valuable materials for using in 1.3 mu m fiber-amplifiers and 2-5 mu m mid-infrared laser devices. (C) 2013 Elsevier B.V.
