Sr₂CeO₄具有新型独特的一维链状结构,它不仅可作为蓝色荧光材料,而且还是良好的基质材料。由于其性能优异,同时又适合稀土掺杂的基质材料,被人们誉为第二代长余辉发光材料,是发光材料的发展方向之一,所以Sr₂CeO₄的研究引起了人们的广泛关注。本文主要介绍了评价发光材料性能优劣的一些指标,Sr₂CeO₄荧光体的结构、发光的原因机理以及影响发光的一些因素。介绍了发光材料的常见合成方法：燃烧法、高温固相法、微波法、化学共沉淀法、溶胶-凝胶法等,并指出了各种合成方法优点和需解决的问题,提出了解决问题的设想。此外还介绍了发光材料的表征手段,及稀土掺杂的Sr₂CeO₄的发展状况,并提出了今后研究的设想。

Sr₂CeO₄, with its new unique one dimensional chain structure, can not only be used as a blue fluorescent material, but also serve as a good matrix material. Sr₂CeO₄ was much studied as one of the development direction of light-emitting materials due to its excellent performance, and as a rare earth doped matrix material, hailed as the second generation of long-lasting light-emitting materials. This paper reviews some evaluation indicators of luminescence properties, the mechanism of luminescence and the influencing factors on the luminescence. Synthetic methods of samples such as the combustion method, the high-temperature solid-phase method, the microwave method, the chemical co-precipitation method, and the sol-gel method are discussed with their advantages and the existing problems. Meanwhile, some ideas about solving the problems are put forward. The characterization of the light-emitting materials and the development of rare-earth-doped Sr₂CeO₄ in the context of the future research are also addressed.
