文摘为研究稀土发光纳米晶的微观结构和形貌对发光性能的影响,用凝胶-微波干燥法和凝胶-烘箱干燥法制备了花状形貌的Sr3Al2O6晶体.研究了微波干燥和烘箱干燥两种不同的干燥方式对溶胶-凝胶法制备的Sr3Al2O6∶Eu2+发光粉体粒径、形貌、团聚程度、干燥时间及发光性能等的影响,结果表明采用微波干燥不仅可以大大缩短干燥所需时间,而且有利于减弱Sr3Al2O6∶Eu2+发光粉料的团聚和团聚程度,制得了颗粒分散均匀、团聚程度低、发光强度高的Sr3Al2O6∶Eu2+花状形貌粉体.研究了Sr3Al2O6∶Eu2+发光粉体的新型形貌对发光性能的影响,微波干燥法制备的均匀分散的花状形貌发光粉体发光强度高,余辉时间长达20 min.
