| 摘 要： | Trivalent cerium-doped yttrium aluminum garnet （YAG：Ce3＋） phosphors are synthesized by solid-state reaction method through using （Yl-xCex）203 solid solutions as precursors. Solid solubility limits of Ce3＋ replacing y3＋ in Y203 and YAG are determined to be 40% and 7.5%, respectively, based on the relationship between the lattice param- eter and chemical composition. Using （Y1-xCex）203 as precursors we synthesize YAG：Ce3＋single phase at 1450 ~C and N2 atmosphere. However, under the same conditions using CeO2 there exists a second phase YA103 as impurity. The photoluminescence intensity of YAG：Ce3＋ increases monotonically with the increase of Ce concentration until it reaches a maximum at solid solubility limits of Ce3＋ in YAG.
