Fabrication and Luminescence Properties of Y1.34Gd0.60Eu0.06O3 Transparent Ceramics

Abstract

Abstract: Y_1.34Gd_0.60Eu_0.06O₃ nanopowders with high sinterability were prepared via a complex co-precipitation
method. The nanopowder obtained has an average particle size of 30～40nm, weakly agglomerate after calcining at 850℃ for 2h. After dry-pressed and
isostatic pressed at 200MPa, the green body can be sintered to transparency at 1800℃ for 6h. The as-sintered transparent ceramics show
intense red luminescence at 610nm under 250nm UV excitation, corresponding to ⁵D₀-⁷F₂ transition of Eu³⁺ ion.

Key words: Y_1.34Gd_0.60Eu_0.06O₃, transparent ceramics, luminescent properties
