摘　　要：采用室温球磨固相化学反应法制备蓝色荧光粉BaMgAl10O17:Eu2+的基质材料,借鉴表面扩散原理对蓝粉进行铕元素的掺杂,用活性碳粉还原得到BaMgAl10O17:Eu2+。XRD分析表明:制得的基质粉末为BaMgAl10O17;SEM形貌观察及荧光测试分析表明:合适的表面活性剂可以实现超细化,同时可有效提高粉体的分散度和分布均匀性,改善粒子的形貌,而且可以显著提高荧光粉的发光强度。The host of fluorescence powder BaMgAl10O17：Eu^2＋ was prepared by the ball-grinding solid state reaction at room temperature. Then surface diffusion theory was applied to adulterate Eu to the blue phosphor. BaMgAl10O17：Eu^2＋ was gained after deoxidized by active carbon powder. The host powder was demonstrated to be BaMgAl10O17 by X-ray Diffraction （XRD）. Optimum surfactants are helpful to improve the dispersity and decrease the granularity of the products. Furthermore, it can enhance luminescence intensity dramatically.
