Abstract

The Sm3+ ions were doped tellurite glasses with composition (55-x) TeO2-10ZnF2- 35BaO-xSm2O3 (where x = 0.00, 0.05, 0.10, 0.50, 1.00 and 1.50 in mol%) to investigate the physical, the optical, the luminescence and structural properties. The functional groups can be identified using FT-IR spectra of Sm3+ in the glasses. The most intense peak from emission spectra is at 600 nm (4G5/26H7/2) corresponding to reddish-orange color. The oscillator strengths were resolved from the absorption spectra and then used to calculate the Judd - Ofelt (J - O) intensity parameters. The radiative properties were calculated by J - O intensity parameters for various transitions in tellurite glass matrices. According to the results of stimulated emission cross section, lifetime and the branching ratio of the emission transition 4G5/26H7/2, it is promised that 0.50 mol% of Sm2O3 doped tellurite glasses is the potential laser material.
