White light emitting diode (WLED) is considered as a fourth-generation green light source and presents some applications in lighting fields due to its advantages of long service life, high luminous efficiency, and free environmental pollution. The exisiting main commercialization use of WLED is a blue chip combined with YAG:Ce3+ phosphor. However, the luminescence performance of the WLED gradually declines with the increase of temperature due to a poor thermal conductivity of the resin encapsulating the phosphor, thus becoming difficult to apply to high-power lighting. It is necessary to obtain the superior phosphor materials with high quality and stability. In recent years, directionally solidified Al2O3/YAG:Ce3+ eutectic phosphor composite is considered as a novel bulk phosphor material for a high-power WLED lighting, which is expected to substitute conventional phosphors, due to its excellent luminous properties, high temperature strength and thermal stability, low power consumption as well as superior quantum efficiency. This review summarized the main preparation technologies of Al2O3/YAG:Ce3+ eutectic phosphor composite. Meanwhile, the microstructure, luminescence mechanism, and influential factors of the Al2O3/YAG:Ce3+ eutectic phosphor composite were analyzed. In addition, the future development direction was also discussed.

白色发光二极管(WLED)具有长寿命、高光效、节能环保等独特优势,是目前公认的第四代绿色照明光源,在照明等高技术领域具有重要的应用前景。目前,WLED的主要实现形式为蓝光芯片搭配YAG:Ce3+荧光粉,封装荧光粉的树脂导热性较差,导致LED的发光性能随温度的升高逐渐下降,难以应用于大功率照明。因此,如何获得高质量、高稳定性、无需树脂的块体荧光材料成为提升WLED发光效率和应用可靠性的关键。近年来,利用定向凝固方法制备的高性能Al2O3/YAG:Ce3+块体共晶荧光复合陶瓷以其优良的发光性能、高温强度、热稳定性以及低的背散射损失和高量子效率,被认为是一种有望替代荧光粉、用于大功率WLED照明的新型块体荧光材料。总结了近年来发展的定向凝固Al2O3/YAG:Ce3+共晶荧光复合陶瓷的主要制备方法,阐述了共晶荧光复合陶瓷的凝固组织、发光机理以及影响发光性能的主要因素,展望了白光LED用Al2O3/YAG:Ce3+共晶荧光复合陶瓷的发展趋势。

白色发光二极管(WLED)具有长寿命、高光效、节能环保等独特优势,是目前公认的第四代绿色照明光源,在照明等高技术领域具有重要的应用前景。目前,WLED的主要实现形式为蓝光芯片搭配YAG:Ce3+荧光粉,封装荧光粉的树脂导热性较差,导致LED的发光性能随温度的升高逐渐下降,难以应用于大功率照明。因此,如何获得高质量、高稳定性、无需树脂的块体荧光材料成为提升WLED发光效率和应用可靠性的关键。近年来,利用定向凝固方法制备的高性能Al2O3/YAG:Ce3+块体共晶荧光复合陶瓷以其优良的发光性能、高温强度、热稳定性以及低的背散射损失和高量子效率,被认为是一种有望替代荧光粉、用于大功率WLED照明的新型块体荧光材料。总结了近年来发展的定向凝固Al2O3/YAG:Ce3+共晶荧光复合陶瓷的主要制备方法,阐述了共晶荧光复合陶瓷的凝固组织、发光机理以及影响发光性能的主要因素,展望了白光LED用Al2O3/YAG:Ce3+共晶荧光复合陶瓷的发展趋势。

White light emitting diode (WLED) is considered as a fourth-generation green light source and presents some applications in lighting fields due to its advantages of long service life, high luminous efficiency, and free environmental pollution. The exisiting main commercialization use of WLED is a blue chip combined with YAG:Ce3+ phosphor. However, the luminescence performance of the WLED gradually declines with the increase of temperature due to a poor thermal conductivity of the resin encapsulating the phosphor, thus becoming difficult to apply to high-power lighting. It is necessary to obtain the superior phosphor materials with high quality and stability. In recent years, directionally solidified Al2O3/YAG:Ce3+ eutectic phosphor composite is considered as a novel bulk phosphor material for a high-power WLED lighting, which is expected to substitute conventional phosphors, due to its excellent luminous properties, high temperature strength and thermal stability, low power consumption as well as superior quantum efficiency. This review summarized the main preparation technologies of Al2O3/YAG:Ce3+ eutectic phosphor composite. Meanwhile, the microstructure, luminescence mechanism, and influential factors of the Al2O3/YAG:Ce3+ eutectic phosphor composite were analyzed. In addition, the future development direction was also discussed.
