中文摘要：

在YAG∶Ce3＋荧光粉中加入黄色PbO,得到YAG∶Ce3＋,Pb2＋荧光粉。比较了PbO掺入前后荧光粉的发射光谱,结果表明：PbO的加入可以使Ce3＋的黄光发射发生红移,增加了光谱的红光成分;同时,Ce3＋的发射强度也有所增加,形貌表明PbO可能起助熔作用,在PbO的含量为5%时,强度增加10%。比较YAG∶Ce3＋,Pb2＋和YAG∶Ce3＋的温度特性曲线,证明YAG∶Ce3＋,Pb2＋荧光粉的温度特性好于YAG∶Ce3＋荧光粉。

英文摘要：

Doubly doped YAG ： Ce3＋ , Pbz＋ phosphor was obtained by doping YAG ： Ce3＋ phosphor with PbO. Compared with the emission spectra of YAG ： Ce3＋ phosphor without PbO, the Cea＋ emission band of YAG ： Ce3＋ , Pb2＋ shifts to longet wave, which can enhance the red component of spectrum. Meanwhile, the intensity of Ce3＋ emission is increased by 10% when the con- centration of PbO is 5%, SEM image indicates that PbO may act as a flux. Temperature-dependent emission spectra of YAG ： Ce3＋ , Pb2＋ phosphor show a better thermal quenching characteristics than YAG ： Ce3＋ phosphor.
