Cooperative energy transfer in silica fibres doped with ytterbium and terbium
Resonant excitation Yb<sup>3+</sup> at 974 nm (10267 /cm) in codoped Yb<sup>3+</sup>-Tb<sup>3+</sup> silica based fibres has lead to luminescence clearly being visible from the Tb3+ 5D4 level (20661 /cm). Through time resolved fluorescence measurements we have bee...
