摘　　要：硅基氮(氧)化物荧光粉因其具有结构特性多样化、发光效率高、热稳定性和化学稳定性好等优点,在白光LED领域有着广阔的应用前景。自20世纪末以来,多种基质结构的硅基氮(氧)化物荧光粉陆续被发现和报道。本文综述了近年来硅基氮(氧)化物荧光粉的基质体系和发光性能,分析总结了硅基氮(氧)化物荧光粉的制备方法及发光性能改进的研究新进展。最后,展望了硅基氮(氧)化物荧光粉的研究发展方向,指出(Ca,Sr)AlSiN_3:Eu^(2+)红色荧光粉需进一步提高发光效率,La_3Si_6N_(11):Ce^(3+)黄色荧光粉需进一步完善发光性能与制备工艺、晶体结构间的相互影响规律,而β-Sialon:Eu^(2+)绿色荧光粉需深入研究激活剂Eu^(2+)的有效溶入机制,提高其发光性能和发光效率。此外,开发更多具有更优异性能的新型硅基氮(氧)化物荧光粉,探索工艺条件和缓、成本低廉、适于工业化量产的简易的制备技术、装备和路线,也是氮(氧)化物荧光粉研制需继续努力的方向。The silicon-based （oxy）nitride phosphors were considered as promising candidate materials for phosphor-converted white LED owing to their structure characteristics diversification, high luminous efficiency, high thermal stability and chemical stability. Since the end of last century＇, a variety of host structure of silicon-based （oxy） nitride phosphors have been found and reported. Here different kinds of silicon-based （oxy） nitride phosphor host systems and their luminescence properties were reviewed. The latest re- search progress in the improvement of the preparation methods and luminescence properties of silicon-based （oxy） nitride phosphors were intensively summarized and discussed. At last, the research and development trend in white LED of silicon-based （oxy） nitride phosphors were pointed out. （Ca,Sr）AlSiN3 ：Eu2＋ red phosphors need to be further improved in the luminous efficiency. La3Si6N11 ： Ce3 ＋ yellow phosphors need to be further studied on the interactional relationship of the luminescent properties with the synthesis tech- nologies and the crystal structures. β-Sialon：Eu2＋ green phosphors need to be in-depth investigated on the effective introduction mechanism of the activator Eu2＋ into the β-Sialon host and the improvement of luminescent properties and luminous efficiency, and so on. In addition, the development of more new silicon-based （oxy）nitride phosphors with more excellent properties, and the exploration of simple synthesis technologies, equipments and processes with moderate condition, low cost and suitable for industrialized production are also directions for the development of silicon-based （oxy）nitride phosphors.
