钛酸锌(ZnTiO3)作为一种有应用潜力的光致发光材料,近年来得到了研究者的广泛关注.但目前的相关报道都是围绕立方相ZnTiO3的发光性能展开论述,没有关于六方相ZnTiO3发光性能的研究.以去离子水作溶剂,采用溶胶-凝胶法制备出掺杂Ni2+的六方相ZnTiO3粉体,利用X射线衍射仪对其物相结构做了分析,使用荧光分光光度计对其激发光谱和发射光谱进行了表征,并将其与纯六方相ZnTiO3的发光性能做了对比分析.结果表明,在600℃制备出的样品主晶相均为纯六方相ZnTiO3,Ni2+的引入并没有改变ZnTiO3的物相结构.Ni2+掺杂量在3.0％以下的样品发射峰强度增大,原因是Ni2+作为能量传递介质,提高了样品的发光效率；但Ni2+掺杂量达到4.0％时,发生了浓度猝灭现象.Ni2+在ZnTiO3中位于原Zn2+的格点位置.
