چکیده انگلیسی
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 5â¯at% Yb:Lu2O3 powders with the mean particle size of 67â¯nm were obtained when calcined at 1100â¯Â°C for 4â¯h. Using the synthesized powders as starting material, we fabricated 5â¯at% Yb:Lu2O3 ceramics by pre-sintering at different temperatures combined with HIP post-treatment. The influence of pre-sintering temperature on the densities, microstructures and optical quality of the 5â¯at% Yb:Lu2O3 ceramics was studied. The ceramic sample pre-sintered at 1500â¯Â°C for 2â¯h with HIP post-treating at 1700â¯Â°C for 8â¯h has the highest in-line transmittance of 78.2% at 1100â¯nm and the average grain size of 2.6â¯Âµm. In addition, the absorption and emission cross sections of the 5â¯at% Yb:Lu2O3 ceramics were also calculated.
