摘    要:采用传统固相法和水热法成功地制备出棒状La2Zr2O7:Eu3+荧光粉. 利用X射线粉末衍射仪、透射电镜和荧光光谱仪等分析了产物的结构、形貌和发光特性. 结果表明红色荧光粉La2Zr2O7:Eu3+有良好的晶相,属于立方结构,空间点群为Fd3m; 其形貌主要为纳米棒, 平均直径约47 nm, 长度为50~700 nm. 并对纳米棒的生长机理进行了探讨. 在466 nm蓝光激发下,La2Zr2O7:Eu3+荧光粉能发射出Eu3+的特征红色荧光,发射主峰位于616 nm处,归属于Eu3+5DO7F2超灵敏电偶极跃迁.此外,在产物的发射光谱中能够观察到5D17FJ (J=0, 1, 2)跃迁和5D17FJ (J=1, 2, 4)跃迁的劈裂峰,这说明Eu3+处在低对称性的晶体场格位中.

关 键 词:La2Zr2O7:Eu3+,烧绿石结构,纳米棒荧光性能
