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.
