[摘要]：It is presented the Nd doping of the glassy ZnO-CdO-TeO2 ternary system. The Nd-doped oxide glasses were prepared by conventional melt-quenching method using three different compositions from this system. X-rays diffraction (XRD) diagrams in these materials reveal that they are basically vitreous structure. Infrared (IR) spectra of the glasses showed the characteristic bands at 665, 670, and 675 cm(-1), which correspond to the trigonal structure of TeO3. The presence of Nd3+ was detected in the visible and infrared region of the spectra by optical absorption (OA) measurements of the band gap and by photoluminescence (PL) experiments. Glasses showed light emission due to the transition: F-4(3/2) -> I-4(9/2). Differential thermal analysis (DTA) of these glasses have shown that T-g temperatures are in the 465-485 degrees C and T-c in the 800-1000 degrees C ranges. (C) 2011 Elsevier B.V.
