Abstract
YTH doped bismuth boro-tellurite glass (68%TeO2-10%Bi2O3-20%B2O3-1%Yb2O3-0.5Tm2O3-0.5%Ho2O3) was created using traditional melt-quench techniques. The intense red upconversion emission at 660 nm (Red, Ho: 5F5→ 5I8) and lack of the typically observed 485 nm emission (Blue, Tm: 1G4 →3H6) were found to be caused by the direct sensitising effects of Yb ions (Yb →Ho) and indirect sensitising and self-depopulating effects of Tm ions (Yb → Tm → Ho). As TBBYTH-glass exhibits the maximum emission intensity at 660 nm, it is considered to be a potential active bismuth boro-tellurite glass for the development of red fibre lasers.
