摘要

采用高温固相法合成了不同浓度Ce3+ 掺杂的AlON荧光粉. 通过X射线和扫描电镜分析了荧光粉的物相和显微结构, 且利用荧光光谱仪测试了AlON:Ce3+荧光粉的发光光谱.结果表明, 荧光粉在305 nm紫外激发下发射390 nm为中心的蓝光.温度依赖荧光谱测试发现, AlON:Ce3+荧光粉在150 ℃ 下发射强度能保持室温发射强度的86%.因此, 该荧光粉是大功率白光发光二极管用最佳荧光粉的候选材料之一.

Abstract

In this paper, AlON phosphors doped with Ce3+ are prepared by solid-state reaction method. Phases, microstructures and optical properties of the synthesized phosphors are characterized by X-ray diffraction and scanning electron microscopy and photoluminescence. The results indicate that AlON3+:Ce phosphors emit the blue light centered at 390 nm under the excitation of 305 nm. The emission intensity of AlON:Ce3+ at 150 ℃ is about 86% of that measured at room temperature. It demonstrates that the AlON:Ce3+ has a great potential in applications of high-density white light-emitting diodes.
