英文摘要	Ytterbium doped lutetium oxide (Yb:Lu2O3) transparent ceramics were fabricated by vacuum sintering combined with hot isostatic pressing (HIP) of the powders synthesized by the co-precipitation method. The effects of calcination temperature on the composition and morphology of the powders were investigated. Fine and well dispersed 5 at% Yb:Lu2O3 powders with the mean particle size of 67 nm were obtained when calcined at 1100 degrees C for 4h. Using the synthesized powders as starting material, we fabricated 5at% Yb:Lu2O3 ceramics by presintering at different temperatures combined with HIP post-treatment. The influence of pre-sintering temperature on the densities, microstructures and optical quality of the 5at% Yb:Lu2O3 ceramics was studied. The ceramic sample pre-sintered at 1500 degrees C for 2h with HIP post-treating at 1700 degrees C for 8h has the highest in-line transmittance of 78.2% at 1100 nm and the average grain size of 2.6 mu m. In addition, the absorption and emission cross sections of the 5 at% Yb:Lu2O3 ceramics were also calculated.
