Abstract

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 σ_em-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 ⁴F_9/2→⁶H_J (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 σ_em-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 ⁴F_9/2 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. © 2013 American Institute of Physics.
