With the development of LED technique, red- M 2 Si 5 N 8 ( M =Ca, Sr, Ba) phosphors gradually become an important kind of three-primary-color phosphors. With the increasing of the patent applying amount, the broad application prospects of M 2 Si 5 N 8 phosphors have received great attention at home and abroad. To understand the application status of M 2 Si 5 N 8 phosphors comprehensively and promote the development of research and technique ultimately, this paper firstly reviews the patent applying amount over the years, important applicants and technical evolution of basic patents on preparing the phosphors. The synthesis methods are classified and compared. The creative points are concluded. The paper may be helpful for those persons in the field to acquire recently technical development on related industries, develop and protect valid patents. 发光材料 制备 专利综述 M 2 Si 5 N 8 phosphor preparation patent review M 2 Si 5 N 8 世界知识产权组织. 国际专利分类表 [M]. 北京: 知识产权出版社, 2008.
