摘要

采用化学共沉淀法合成了镓取代的掺铈钇铝石榴石 (YAGG:Ce) 荧光粉.通过TG和FTIR分析了样品合成过程中的反应机理，根据XRD晶相结构和XPS表面元素分析讨论了Ga取代后晶体结构与表面元素组成，并用光谱分析了Ga掺杂浓度对样品发光性能的影响状况.实验结果表明，镓离子取代基质中的铝离子后XRD图谱峰出现向小角度方向移动的现象，发光光谱的强度受Ga取代浓度的影响.

Abstract

A series of Gallium-substituted Cerium-doped yttrium aluminum garnet (YAGG:Ce) phosphors were produced by co-precipitation. The formation process and structure of the Ga

-substituted phosphor powders are characterized by TG

FTIR

XRD and XPS

and the impacts of Ga

concentration on the luminescence properties have been investigated. The results show that the blue shift occurs after Ga3+ replaces Al3+ in matrix

and the intensity of emission spectrum is affected by the concentration of Ga
