摘要
固态照明具有功率大、亮度高、体积小、节能环保等优点,已成为21世纪最有前景的照明技术。作为固态照明关键材料,荧光材料的性能直接决定固态照明器件的显色指数、流明效率和可靠性等技术参数。相较于荧光单晶、荧光玻璃、荧光薄膜及量子阱,荧光陶瓷因具有优异的热学和光学性质及微观结构易调控等特点,被认为是综合性能最优的大功率固态照明用荧光材料。未来,荧光陶瓷将在汽车大灯、户外照明、激光电视、激光影院等领域得到更广泛的应用和发展,具有广阔的市场前景。本文探讨了大功率固态照明用荧光陶瓷的设计原则,重点介绍了目前研究相对较多的氧化物荧光陶瓷(主要指钇铝石榴石结构)和氮(氧)化物荧光陶瓷的研究进展,最后对大功率固态照明用荧光陶瓷的未来发展方向进行了展望。
Due to high power,high brightness,small size,energy saving,and environment friendliness,solid-state lighting has been becoming the most promising lighting technology in this century.As the key material of solid-state lighting,the luminescent properties of phosphors directly determine the crucial parameters such as the color rendering index,luminous efficacy and reliability of solid-state lighting devices.Compared with single crystals,phosphor glasses,phosphor films and quantum-well LEDs,phosphor ceramics have become the most excellent phosphor materials for high-power solid-state lighting due to its excellent thermal and optical properties and easy control of microstructure.In the future,phosphor ceramics are expected to be more widely used and developed in automotive headlights,outdoor lighting,laser TVs,laser cinema projectors,and other fields,and have a broad market prospect.In this review,design principles of high-power solid-state lighting phosphor ceramics are put forward firstly,and then research progress of oxide phosphor ceramics(mainly referring to Y_(3)Al_(5)O_(12))and nitrogen/oxynitride phosphor ceramics is reviewed mainly.Finally,the development of phosphor ceramics for high-power solid-state lighting is prospected.
