摘要
Multichannel transition visible and near-infrared (NIR) fluorescences have been captured in Dy3-doped fiber-adaptive Na2O-ZnO-PbO- GeO2-TeO2 glasses. The maximum stimulated emission cross-sections σem-max were derived to be 0.33 × 10 -21, 3.66 × 10-21, and 0.67 × 10-21 cm2 for conventional visible emissions assigned to 4F9/2→6HJ (J 15/2, 13/2, and 11/2) transitions, respectively. Infrequent multi-peak NIR emissions were recorded in the spectral range of 900-1500 nm, among which the values of σem-max were solved to be 1.05 × 10-22 and 1.56 × 10-22 cm2 for ∼1.02 and ∼1.18 μm emission bands. Internal quantum efficiency for the 4F9/2 level and external quantum yield for visible emissions of Dy3 were determined to be 88.44 and 12.38, severally. Effective multichannel radiative emissions reveal a potential in developing fiber-lighting sources, tunable lasers, and NIR optical amplifiers.
