以Mn2＋、Eu3＋、Gd3＋为第二激活剂,采用微波均水热方法,制备稀土离子共掺杂的YAG：Ce3＋荧光粉,讨论了掺杂离子对YAG：Ce3＋荧光粉性能的影响,并对物相组成以及晶体结构进行了分析。结果表明,Gd3＋的掺杂对荧光粉发光性能影响明显,能够提高其荧光效率,而Mn2＋、Eu3＋引起荧光猝灭。上述三种离子掺杂没有改变YAG晶体结构。

As the second activators, Mn2＋,Eu3＋,Gd3＋ ions were added to synthesize YAG：Ce3＋ phosphors by the microwave hydrolysis process, the effects of rare-earth ions on the properties of the co-doped phosphors were studied, and the phase composition and crystal structure were analyzed. The result shows that the influence of Gd3＋ ions on the luminescence property of the phosphor was obvious, and the fluorescence efficiency was enhanced. The co-doping of Mn2＋ and Eu2＋ ions quenched fluorescence. These dopants did not change the crystal structure of YAG.
