dc.description.abstract | The absorption spectra in the visible and near IR regions for Ga0.017Ge0.25As0.083S0.65 are investigated. The visible luminescence from Dy3+, and co-doped with Ho3+ and Dy3+ ions embedded in Ga0.017Ge0.25As0.083S0.65 glass hosts at room temperature and at T=10 K is reported, when pumping with an Ar+-ion laser at λ=488 nm. Fluorescence emissions at around 1300 nm was observed for Dy3+ doped glasses with wavelength pumping at 950 nm. Energy transfer from Ho3+:5F3 level to Dy3+:4F9/2 level increase the visible emission efficiency at 650 nm and at ~1300 nm in the co-doped glasses. The investigated Ga0.017Ge0.25As0.083S0.65 glasses doped with Dy3+ are promising amplifier materials for 1300 and 1500 nm fiber optic telecommunication windows. | en_US |
