Paper Title:
Optical Characterization of Eu3+ and Tb3+ Ions Doped Zinc Lithium Borotellurite Glasses
  Abstract

This paper reports on the development and spectral results of Eu3+ and Tb3+ ions doped zinc lithium boro tellurite glasses in the following composition: 20TeO2 - (60-x) B2O3 -10 ZnO-10Li2O-x Eu2O3 20TeO2 - (60-x) B2O3 -10 ZnO-10Li2O-x Tb4O7 (where x= 0.125, 0.25, 0.375, 0.5 , 0.625 mol %) The measured emission spectrum of Eu3+ glass have revealed five transitions (5D0→7F0, 7F1, 7F2, 7F3 & 7F4) at 578 nm, 592 nm, 612 nm, 643 nm, 701 nm respectively with λexci=392 nm (7F0→5L6) .In the case of Tb3+ glasses four emission transitions such as (5D4→ 7F6, 7F5,7 F4 & 7F3) that are located at 488 nm, 543 nm, 583 nm and 614nm respectively have been measured with λexci=376 nm. For all these emission bands decay curves have been plotted to evaluate their life times.
