“…The quaternary Ga-Ge-Sb-S glass system doped with Nd 3+ ions was selected to avoid the presence of arsenic. This system contains gallium, which allows a better solubility of RE 3+ ions than other chalcogenide matrices without gallium [16][17][18][19]. Among this quaternary system, the nominal composition of Ga 5 Ge 20 Sb 10 S 65 was especially preferred for its stability against crystallization and suitable thermo-mechanical properties favoring fiber drawing.…”

With high refractive indices, appropriate solubility of rare earth, low phonon energy and transparency from the visible to 10 µm, a GaGe -Sb-S system allows emission from Nd 3+ ions in the near-and mid-IR spectral ranges. The glass transition temperature, density, expansion coefficient, and near and mid-IR refractive indexes were measured on bulk samples. Their glass network structures were analyzed by Raman scattering spectrometry, NMR of 71 Ga and extended X-ray absorption fine structure (EXAFS, K-edge of Ga, Ge, Sb, S and Nd). The absorption and emission spectra of neodymium doped sulfide glasses were recorded from the visible to the mid-IR. Excited state lifetimes were measured for several transitions. The lifetimes decrease with the concentration of Nd 3+ , especially for the 4 I 13/2 and 4 I 11/2 levels. The spectroscopic parameters were determined by the Judd-Ofelt method, allowing the calculation of cross-section emissions and the evaluation of quantum yields. Optical attenuation and emission measurements of fiber were also performed with a broad 4.7-5.7 µm emission band in the mid-IR.

“…The value of lifetime agreed with previous studies on Nd 3+ doped chalcogenide glasses, but was signicantly shorter than in oxide glasses. 5,24,26,27 This reduction of the lifetime is characteristic of optical materials with high refractive index and consequently high s em s product. 7 On the other hand, the critical concentration found for Se-GLS glass resulted to be comparable to those reported for silicates, phosphates and other well characterised oxide and halide glasses.…”
