The effect of Eu3+ ions concentration on the optical properties of TeO2-BaO-Eu2O3 glass was studied. The absorption intensity of the charge-transfer band was observed as a function of Eu3+ ions concentration. The absorption intensity relative to that of the host increased with the increase of the Eu3+ ions concentration. The strong emission peaks lied in 594 and 615 nm under 394 nm excitation for all the samples. The emission intensity of 5D0→ 7F2 transition changed with Eu3+ ion concentration with respect to that of 5D0→ 7F1 transition. Phonon sidebands were related to the doped concentration of the samples.
