摘要：综述钇铝石榴石体系荧光陶瓷、多铝酸盐体系荧光陶瓷、氮化物体系荧光陶瓷3类荧光陶瓷材料的发光机理、制备工艺及其应用进展。荧光陶瓷材料具有热力学性能好、机械性能优异、良好的化学稳定性和微观结构可调等优点。现有的LED照明设备多使用树脂封装荧光粉，其热稳定性差，无法在大功率、长时间的应用场景中使用，故此，采用热力学性能好、机械性能优异、具有良好的化学稳定性和微观结构可调等优点的荧光陶瓷材料，取代传统树脂封装荧光粉制备LED照明设备。荧光陶瓷材料当前依然存在制备条件苛刻、工艺复杂和无法实现全色谱发光等问题，不能适用于规模化生产应用，这是接下来业界的主要研究方向。

Abstract：In this paper,the luminescence mechanism,preparation process and application progress of fluorescent ceramics with yttrium aluminum garnet system,aluminate system and nitrite system are reviewed. Fluorescent ceramic materials have the advantages of good thermodynamic properties,excellent mechanical properties,good chemical stability and adjustable microstructure.The existing LED lighting equipment mostly uses resin-encapsulated phosphors,which have poor thermal stability and cannot be used in high-power and long-term application scenarios. Therefore,fluorescent ceramic materials with good thermodynamic properties,excellent mechanical properties,good chemical stability and adjustable microstructure are used to replace the traditional resin encapsulated phosphor for the preparation of LED lighting equipment. However,fluorescent ceramic materials still have some problems,such as harsh preparation conditions,complex process and inability to achieve full chromatographic luminescence,which are not suitable for large-scale production and application. This is also the main research direction of the industry in the future.

Keywords：fluorescent ceramics; luminescence principle; yttrium aluminum garne; aluminate; nitride
