摘要：

Yb3+ doped Lu2O3 transparent ceramics were fabricated by the solid-state reaction method and sintered in H-2 atmosphere. Structural and spectroscopic properties of Yb:Lu2O3 ceramics were studied. The Yb:Lu2O3 ceramic structure, and the lattice parameter are refined with the Rietveld method. Yb:Lu2O3 has broad absorption and emission bands with a long fluorescence lifetime (1.31 ms). The energy level diagram is calculated based on the absorption and emission spectra. Yb3+ in Lu2O3 ceramics exhibits a big splitting energy of the F-2(7/2) ground state (1023 cm(-1)). Furthermore, the gain cross-section (sigma(g)) is estimated with different beta values. (C) 2011 Elsevier B.V. All rights reserved.
