以Ba(NO3)2、Al(NO3)3·9H2O、Mg(NO3)2·6H2O和Eu(NO3)3为初始原料,首次用硝酸盐热分解法在1300℃左右合成了单相Ba1-xMgAl10O17:xEu2+(0.02≤x≤0.16)并表征了其发光特性.结果表明,硝酸盐热分解法的合成温度比传统的高温固相法降低了近300℃,且合成出的荧光粉体色白、亮度好、结构松散且无烧结现象.在254 nm紫外光激发下,Ba1-xEuxMgAl10O17(0.02≤x≤0.16)的最强峰在450 nm左右,属于Eu2+的4f65d→4f7(8S7/2)宽带允许跃迁;当x=0.1时发光强度最高.用硝酸盐热分解法合成的样品较传统高温固相法所得样品的发光强度强.
