Abstract

The near-infrared emission properties in low-phonon (805 cm−1) gallo-germanate glasses and their glass fibers co-doped with Yb3+/Ho3+ and Yb3+/Tm3+/Ho3+ have been investigated. Emission bands centered at about 2 μm correspond to 3F4 → 3H6 (Tm3+) and/or 5I7 → 5I8 (Ho3+) transitions. The spectral widths of emission lines are relatively large and their values for glass samples co-doped with 0.7Yb2O3/0.15Ho2O3 and 0.5Yb2O3/0.4Tm2O3/0.05Ho2O3 are close to 159 nm and 343 nm, respectively. Gallo-germanate glasses characterized by broadband emission at 2 μm have been used for fabrication of glass fibers. The effects of fibers length on their near-infrared luminescent properties have been also analyzed in details.
