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。
