Paper Abstract

The paper presents energy transfer in tellurite glass from the system TeO2 - GeO2 - PbO - PbF2- BaO - Nb2O5 - LaF3 doped with Yb3+/Tm3+ ions. Under the excitation of 976 nm laser a strong blue emission (477 nm) corresponding to the transition 1G43H6 in thulium ions was observed. Analysing the influence of the content of Tm3+ ions on the level of luminescence obtained by the mechanism of upconversion it was established that the most effective energy transfer between Yb 3+→ Tm3+ ions took place in the matrix doped in the following proportion: 1 Yb3+:0.1 Tm3+ (%mol). Based on the non-resonant process of energy transfer between Yb3+ and Tm3+ ions the mechanism of upconversion was discussed.
