Paper 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 5D47FJ (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%).
