采用凝胶-燃烧法合成了Sr1.99S1O4∶ Ce0.013+蓝紫色荧光粉,对不同C6H8O7和NH4NO3加入量、H3BO3加入量和电荷补偿剂对Sr1.99SiO4∶Ce0.013+发光性能的影响进行了讨论.结果表明:所得Sr1.99 SiO4∶Ce0.013+样品为α'-Sr2SiO4纯相;其发光谱为220～ 400 nm的近紫外宽带谱,归属于Ce3+离子的5d04f1→5d14f0跃迁;发射光谱是峰值位于405nm的不对称单峰宽带谱,由398nm和427 nm两个高斯峰组成,分别来源于同一发光中心的Ce3+离子5d14f0向基态2F7/2和2F5/2能级的跃迁;C6H8O7和NH4NO3的最佳加入量为n(C6H8O7)/n(Sr(NO3)2)=0.5,n(NH4NO3)/n(Sr(NO3)2) =2.0;H3BO3最佳加入量为12mol％;最佳电荷补偿剂为Li+.
