摘要：
Eu2+ doped gamma-AlON transparent ceramics have been prepared by the solid-state reaction sintering method. The influences of Eu concentration on both strength, transparency and luminescence properties of the as-prepared samples were discussed. The strength and transparency decreased as Eu content increased. Two bands were observed in the emission spectrum of each sample. One (B-1) was narrow and centered at around 401 nm, the other (B-2) was comparatively broader, and the location of its center as well as the intensity ratio of peak values of B-2 to that of B-1 varied with Eu content.
