摘要: Abstract The 2 μm and upconversion emission in low phonon (805 cm −1 ) germanate glass double-clad optical fibers co-doped with 0.7Yb 2 O 3 /(0.07–0.7)Ho ions have been investigated. Glasses the strongest intensity (0.7Yb /0.15Ho /0.35Ho were used as core of (DC) comparative analysis their luminescent properties performed. spectral overlapping between absorption bands at near-infrared (2 μm) DC caused red shifting increase fiber length. Differences luminescence spectra measured for bulk both visible ranges presented discussed details.
