摘要： 本文提出"表面扩散法"的思想并应用于稀土三基色发光材料中蓝色组份BaMgAl10O17:Eu2＋的制备．结果表明，同直接高温因相法制得的荧光体相比，利用表面扩散法制备的蓝色荧光体BuMgAl10O17：Eu2＋,在相同的发光亮度条件下，激活剂Eu2＋的浓度可以大为降低，从而为降低这类材料的成本提出了依据和可能．

Abstract: A surface diffusion method was proposed and applied to prepare blue phosphor BaMgAl10Ol7 :Eu2+. The results show that, compared with the direct synthesis method by common high temperature solid state, the concentration of Eu2+ in the phosphor BaMgAl10O17:Eu2+ prepared by the surface diffusion method can be greatly reduced owing to the activator Eu2+ ions distributed mainly over the surface of the phosphor. It is possible to reduce the cost of this kind of the luminescent materials with the aid of the surface diffusion method.

Key words: surface diffusion method, preparation, blue-emitting phosphor
