Abstract
Yttria (Y2O3) nanopowders were synthesized by a normal precipitation method using (NH4)2SO4 as dispersing agent. Pure Y2O3 powders without any other phase can be achieved by calcining the precursor at 600 °C for 4 h. The precursor and Y2O3 powders were characterized by TG-DTA, XRD, SEM and BET. In this work, 5 at.%Yb:(La0.1Y1.9)2O3 transparent ceramics were made by vacuum sintering at 1650 °C for 10 h. The in-line transmittance of the 5 at.%Yb:(La0.1Y0.9)2O3 ceramics is 81.3% at the wavelength of 1031 nm. The absorption cross-sections of the sample are calculated to be 1.20 Ã 10â20 cm2, 5.74 Ã 10â21 cm2 and 4.18 Ã 10â21 cm2 at 976, 951 and 906 nm, respectively. The emission cross-sections of the emission peak located at around 1031 and 1073 nm are 1.13 Ã 10â20 and 0.42 Ã 10â20 cm2, respectively.
