Preparation of transparent Ce:YSAG ceramic and its optical properties

Fine Ce:YSAG (Y3ScxAl(5−x)O12) powders have been prepared by a chemical combustion method, and Ce:YSAG transparent ceramics was obtained by sintering the powders in hydrogen atmosphere. As Sc2O3 was introduced into the Ce:YAG crystal lattice to partially replace Al, the lattice of YSAG expanded and the optical properties of Ce:YSAG transparent ceramics has greatly changed from that of Ce:YAG ceramics. In Ce:YSAG transparent ceramics, the concentration quenching effect is greatly reduced, and the emission intensity is remarkably enhanced in Ce:YSAG as compared to Ce:YAG ceramics.
