    • An oxyhalide luminescent material doped with rare earth containing metal particles is provided. The formula thereof is Re' 1-x Re" x OX: yM, in which Re' is the first rare earth element, Re" is the second rare earth element, X is F, Cl or Br, M is metal nanoparticles, x is 0.001-0.15, and y is 5x10 -5 -2x10 -3 . A method for producing the luminescent material is also provided. By virtue of metal particles introduced into the oxyhalide luminescent material doped with rare earth and the surface plasma resonance effect of the metal surface, the luminescence intensity of the oxyhalide luminescent material is improved. The good stability, uniform appearance and excellent luminescence intensity of the luminescent material ensure its application in field emission devices. The production method has advantages of simplicity in operating, pollution-free, easy control, less demanding for equipment and suitability for industrialized production.
    • 提供掺杂有稀土金属颗粒的卤氧化物发光材料。 其公式为Re'1-x Re“x OX:yM,其中Re'是第一稀土元素,Re”是第二稀土元素,X是F,Cl或Br,M是金属纳米粒子,x 为0.001-0.15,y为5×10 -5 -2×10 -3。 还提供了制造发光材料的方法。 由于引入到掺杂稀土的卤氧化物发光材料中的金属颗粒和金属表面的表面等离子体共振效应,卤氧化物发光材料的发光强度得到改善。 发光材料的稳定性好,外观均匀,发光强度高,确保了其在场致发射器件中的应用。 该生产方法操作简单,无污染,易于控制,对设备要求不高,适用于工业化生产。
