用燃烧法合成了由Eu^2+离子激活的BaMgAl10O17:Eu^2+蓝色荧光粉,着重研究了助熔剂H3BO3对荧光材料的晶体结构及发光性能的影响。结果表明,添加助熔剂有利于荧光粉的晶化,并增强荧光粉的激发和发射光谱强度;H3BO3的最佳添加量为1.0%,可使BaMgAl10O17:Eu^2+的发光强度提高30%以上。
The Eu^2+ activated blue emitting BaMgAl10O17 : Eu^2+ phosphor for PDP application was prepared by solution combustion method. The effect of H3BO3 as flux on the crystal-structure and luminescence properties of the BaMgAl10O17 : Eu^2+ (BAM) phosphor was mainly investigated. The results show that the flux can help to crystallize the phosphor, and enhances the intensities of excitation and emission spectra of BAM. The optimum content of H3BO3 is about 1.0%, which increased the relative emission intensity of the phosphor over 30%.
