摘要:
以蔗糖或柠檬酸为辅助剂,通过改变超声喷雾热解期间雾滴中溶剂的蒸发方式和溶质聚集状态,进行空心和多孔Y2O3:Eu3+微球的可控合成。探究了辅助剂的种类和比例对微球形貌的影响,提出了空心和多孔Y2O3:Eu3+微球形成机制,并分析了空心和多孔Y2O3:Eu3+微球的晶体结构及光致发光性能。结果表明:Y2O3:Eu3+微球组分均匀,仍保留立方Y2O3结构;添加蔗糖后可获得中空结构,添加柠檬酸则为多孔结构,这归因于添加的蔗糖在雾滴干燥时络合成膜,水分透过膜蒸发,溶质沉积在膜内壁形成空心球壳,而添加的柠檬酸则与溶质形成均匀的螯合物,在高热解温时产生大量原位介孔;空心和多孔Y2O3:Eu3+微球均在611 nm处表现出典型的红光发射,且空心微球的发光强度可达不添加辅助剂合成的实心微球的96.6%。该研究可为大规模产业化合成形貌可控的空心和多孔Y2O3:Eu3+微球提供参考。
