Paper Title:
Emission Spectra of Zinc Oxychloride Tellurite Glass: Effects of Eu3+/Sm3+ Co-Doping
  Abstract

Eu3+ or/and Sm3+ co-doped glasses based on TeO2-ZnO-ZnCl2-Li2O are prepared using the melt quenching technique and the effects of co-doping on the emission spectra of these glasses are examined. The Sm3+ doped glass under 403 nm excitations show emission bands around 561, 598 and 642 nm corresponding to the transitions of 4G5/2 6H5/2, 4G5/26H7/2 and 4G5/26H9/2 respectively. Whereas, in Eu3+ doped glass under 397 nm excitation emission bands appear around 553, 586, 613, 650 and 699 nm that corresponds to the transitions of 5D17F2, 5D0 7F1, 5D0 7F2, 5D07F3 and 5D07F4. In addition, the emission spectra of the Eu3+/Sm3+ co-doped glass under 482 nm excitation consists of five bands in which three are contributed by Sm3+ at 561, 598 and 642 nm and two by Eu3+ at 613 nm and 699 nm respectively. Surprisingly, the emission bands of Eu3+ are still observed in the emission spectra of Sm3+ for the Eu3+/Sm3+ co-doped glasses despite the absence of the excitation wavelength 482 nm in the absorption and excitation domain of Eu3+. This observation is attributed to the partial resonance transfer of the absorption energy from Sm3+ to the Eu3+ ions.
