Abstract: | Ce3+-doped yttrium lanthanum oxide
(Y0.9La0.1)2O3 transparent ceramics is fabricated
with nanopowders and sintered in H2 atmosphere. The spectral
properties of Ce:(Y0.9La0.1)2O3 transparent
ceramics are investigated. There appear two characteristic
absorption peaks of Ce3+ ions at 230~nm and 400~nm,
separately. It is found that Ce3+ ions can efficiently
produce emission at 384~nm from (Y0.9La0.1)2O3
transparent ceramic host, while the emission is completely quenched
in Re2O3 (Re=Y, Lu, La) host materials. |
