摘要：

The Tb3+ ion doped zinc barium boro-tellurite glasses with (30-x) TeO2-30B(2)O(3)-10ZnO-30BaO-xTb(2)O(3) (where x = 0.00, 0.05, 0.10, 0.50, 1.00 and 1.50 mol %) composition were prepared by the melt-quenching method. The characterizations were investigated by measuring UV-Vis absorption, excitation, emission, and luminescence decay spectra. Each absorption spectrum shows three peaks located at about 1894, 1953 and 2210 nm with the intensity increased with increasing concentration of Tb3+ ion. Photoluminescence spectra showed the strong emission bands centered between 520 and 640 nm under Tb3+ ion excitation 484 nm. The optimum concentration of Tb3+ ion concentration in the zinc barium boro-tellurite glasses is 1.00 mol% where the glass sample provides maximum emission intensity located at 542 nm.
