Abstract

Nanophase yttria co-doped with erbium and ytterbium (Er,Yb:Y₂O₃) was successfully synthesized using gas-phase condensation. As-prepared nanoparticles were about 2 nm in diameter, while annealed nanoparticles were about 20 nm in diameter. Two-stage sintering of the nanoparticles led to ceramics with grain sizes of less than 160 nm in diameter, while vacuum sintering led to ceramics with grain sizes of about 5 μm. The annealed nanopowder, as well as the two-stage and vacuum sintered ceramics showed fluorescence from erbium and ytterbium ions.
