摘要(Abstract)：

以价格低廉的水玻璃代替TEOS(正硅酸乙酯)作为硅源,分别在丁二酸铵、柠檬酸三铵辅助下,通过离子交换-溶胶凝胶法合成Sr2MgSi2O7:Eu2+,Dy3+蓝色发光材料。用DTA、XRD、荧光光谱等手段对材料进行分析和表征。结果表明:在丁二酸铵或柠檬酸三铵调节下,前驱体干凝胶煅烧到1100℃转变为高纯度的Sr2MgSi2O7相,其产物疏松,颗粒小,不需研磨或稍加研磨便得细粉;激发光谱在250～450 nm之间都存在一个强度较高的激发带,以柠檬酸三铵辅助得到的Sr2MgSi2O7:Eu2+,Dy3+蓝色发光材料发光性能较好,发射峰位于467 nm附近,余辉时间长。此外对溶胶凝胶的形成机理等进行讨论。
