Abstract

In the article the upconversion luminescence ofTeO₂– GeO₂ – PbO – PbF₂– BaO – Nb₂O₅ – LaF₃ glass system co-doped withYb ³⁺ /Tb ³⁺ under 976 nm laser diode excitation was investigated. The influence of Tb2O3concentration on the luminescent properties was determined. Measured strong luminescence at492, 547, 588, 622 nm correspond to ⁵D₄→⁷F_J (J=6, 4, 3) transitions. Energy transfer (ET) mechanism involved in observed emission was discussed. The highest upconversion emission intensity was obtained in the tellurite glass co-doped with 0.5 Yb₂O₃/0.5 Tb₂O₃ (mol%).
