Spectroscopic Properties of Yb^{3+}/Tb^{3+} Doped Germanate Glasses

In the article the cooperative energy transfer in GeO2 GaO BaO glass system doped with Yb/Tb under 980 nm laser diode excitation was investigated. The in uence of Tb concentration on the luminescent properties was determined. Measured strong luminescence at 489, 543, 586, 621 corresponds to D4 → FJ (J = 6, 4, 3) transitions and luminescence at 381, 415, 435 nm results from D3, G6 → FJ (J = 6, 5, 4) transitions. Mechanism and energy diagram involved in observed emission were discussed. The highest upconversion emission intensity was obtained in the germanate glass doped with 0.7 Yb2O3/0.7 Tb2O3.
