Abstract
In the paper optical properties of 40TeO2 – 20GeO2 – 30(PbO – PbF2)– 10(BaO – Nb2O5 – LaF3) glass system co-doped with Er3+/Tm3+ ions were investigated. The maximum of phonon energy at 790cm-1 in fabricated tellurite glass which was determined by FTIR measurements. Optimisation of glass composition led to the emission at 1820 nm which was observed in results of energy transfer (ET) between Er3+and Tm3+ions under the optical exciting at 976 nm. In order to determine the optimal conditions of ET between exited energy levels of co-doped RE ionsthe dependence of the near-infrared emission upon the thulium ions concentration was studied. In result of that broadband emission in the range from1500 to 1900 nm was achieved owing to the superposition of electronic transition in Er3+ (4I13/24I15/2) and Tm3+ (3F43H6) ions.The highest efficiency of energy transfer was obtained in glass co-doped with 0.2Er2O3/0.3 Tm2O3.
