- Abstract
Barium-tellurite-borate glasses doped with Nd3+ ions were prepared by the melt-quench technique. The amorphous nature of the glasses was confirmed by XRD. The thermal stability of the borate glass was calculated from DTA profiles and TG. The absorption and the luminescence spectra of the glass were measured at room temperature. The spectrum properties of the glass were carried out by using Judd-Ofelt (J-O) theory, the intensity parameters Ω (k= 2, 4, 6) and radiative lifetimes were also calculated. The absorption band at 804 nm has a full-width at half-maximum of 18 nm. The fluorescence spectra revel three major bands. The strongest fluorescence spectrum-emission peak is located at 1062 nm, which can be attributed to the 4F3/2-4I11/2 of the emission band of Nd3+, and the full-width at half-maximum is 29 nm. These properties show that the BaO-TeO2-B2O3 glass doped with Nd3+ ions is expected to be a better laser glass.
