Study on Fabrication of high Luminous Materials for high Performance Display Devices

高性能显示设备的发展需要高亮度材料。The fabrication of new phosphors is examined from the standpoint based on crystal chemistry. Highluminous ceramic materials of Eu D13+ y D13+ y D1 and Tm y D13+ y D1-doped polytantalate of LaTa y D27 y D2O y D219 y D2，gallates and aluminates of SrLaGa·D23·D2O·D27·D2 and CaLaAl·D23·D2O·D27·D2 with layered structures have been·ped。我们发现了这些陶瓷材料在紫外线排放下有很高的临界浓度。The energy migration between EuイD13+イエD1，TbイD13+イエD13+イエD1ions in these？amic materials was strongly affected by the cr？structure。我们提出了一种从平面和晶体结构中的层之间发光距离的观点点的材料设计。

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.
