Structural and spectroscopic characterization of Yb3+ doped Lu2O3 transparent ceramics

Yb3+ doped Lu2O3 transparent ceramics were fabricated by the solid-state reaction method and sintered in H2 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 2F7/2 ground state (1023 cm−1). Furthermore, the gain cross-section (σg) is estimated with different β values.
