The development of high performance display devices requires high luminous materials. The fabrication of new phosphors is examined from the standpoint based on crystal chemistry.High luminous ceramic materials of EuィイD13+ィエD1,TbィイD13+ィエD1 and TmィイD13+ィエD1-doped polytantalate of LaTaィイD27ィエD2OィイD219ィエD2, gallates and aluminates of SrLaGaィイD23ィエD2OィイD27ィエD2 and CaLaAlィイD23ィエD2OィイD27ィエD2 with layered structures have been developed. It was found that these ceramic materials had high critical concentrations under UV exitation. The energy migration between EuィイD13+ィエD1,TbィイD13+ィエD1 and TmィイD13+ィエD1 ions in these ceramic materials was strongly affected by the crystal structure. We propose the material design of thigh luminous ceramic materials from the view points of the distance between luminescent ions in plane and between layers in the crystal structure.

高性能显示器件的发展需要高发光材料。从晶体化学的角度研究了新型荧光粉的制备方法，开发了具有层状结构的EuィイD13+ィエD1，TbィイD13+ィエD1和TMィイD13+ィエD1掺杂的LaTAィイD27ィエD2OィイD219ィエD2，ィイD23ィエD2OィイD27ィエD2和CaLaAlィイD23ィエD2OィイD27ィエD2的高发光陶瓷材料。研究发现，这些陶瓷材料在紫外光激发下具有较高的临界浓度。在这些陶瓷材料中，EuィイD13+ィエD1、TbィイD13+ィエD1和TmィイD13+ィエD1之间的能量迁移受晶体结构的影响很大。从发光离子在晶体结构中的平面间距和层间距的角度出发，提出了大腿发光陶瓷材料的材料设计。
