International audienceHighly stable glasses in the (70 − x)Sb2O3[BOND]20Na2O[BOND]10ZnO[BOND]xEr2O3 (x = 0.25, 0.5, and 1.0 mol%) system have been prepared and investigated by UV-Vis-NIR absorption, near infrared photoluminescence and time-resolved spectroscopy. Judd-Ofelt study has been used to determine the intensity parameters (Ω2, Ω4, and Ω6), spontaneous emission probabilities, branching ratios, and radiative lifetimes (τR) related to the corresponding optical transitions of Er3+ ions. Details of the emission at ∼1530 nm and spectroscopic characteristics such as the stimulated emission cross-section (σe), effectiveband width (Δλeff), quantum efficiency, and the optical gain have been summarized, accounting the role of the increased Er content. The obtained results indicate that these new low phonon energy glasses could be used as a laser medium and for optical amplification in the 1.5 µm region. In particular, the composition containing 0.5 mol% Er2O3 exhibits optimal values of Ω2 (4.5 × 10−20 cm2), Δλeff = 57 nm, σe = 7.28 × 10−21 cm2, τmeas (3.36 ms), and quantum efficiency of the 4I13/2 level of Er3+ ions ∼71%

“…Melts were poured on to a pre-heated steel plate and then annealed at 580 K, just below the T g temperature, for 12 h in order to release the stress in the material. Prisms with typical dimensions of 10 Â 5 Â 1 mm 3 were obtained and all their faces carefully polished for the optical measurements [20,21]. The analysis of the composition of the obtained glasses have been performed by mean of SEM-EDX technique, which confirms the stoichiometric composition of the glasses obtained with differences of less than 10% for the 2.5 mol% of Nd 3 þ glass.…”

“…In terms of high transmission in the VIS-NIR range and low-energy phonons matrices, fluorides seem to be good candidates [5]. Thus the multicomponent glasses combination of tellurium oxides and heavy metal fluorides has been demonstrated to be matrices with the advantages of both component systems, becoming excellent for EDFA at 1.5 lm band when it is doped with Er 3+ ions [7]. Similar multicomponent materials based on doped tellurite glasses had shown promising applications for amorphous solar cells concentrators [8][9][10], taking advantage of the up-and down-conversion processes and incorporating layers above (for down-conversion and photoluminescence) or below (for upconversion) to improve the energy efficiencies [9].…”

a b s t r a c tA study of the optical properties of Nd 3+ ion in TeO 2 -PbF 2 -AlF 3 glasses has been carried out for different Nd 3+ concentrations. Based on the Judd-Ofelt theory, intensity parameters and radiative properties were determined from the absorption spectra. Focusing on the suitability of this host for laser applications, the spectroscopic quality factor v was obtained with a value of 1.07, a value of the order of other compositions proposed as laser hosts. For the most intense emission corresponding with the 4 F 3/2 ? 4 I 11/2 transition (1.06 lm), the absorption and emission and have been calculated with values of 1.20 Â 10 À20 cm 2 , 2.08 Â 10 À20 cm 2 . A positive value for the gain cross-sections has been found for a population inversion factor c of 0.4 in the spectral range from 1060 to 1110 nm. All these results suggest the potentially use of this system as a laser host.
