摘要

It is presented the Nd doping of the gfassy ZnO-CdO-TeO_2 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 TeO_3. 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 photolumines-cence (PL) experiments. Glasses showed light emission due to the transition: 4F_3/2→4I_9/2 Differential thermal analysis (DTA) of these glasses have shown that T_g temperatures are in the 465-485 ℃ and T_c in the 800-1000 ℃ ranges.
