随着水乳比ω

从5变化到35时

粒子发光粉的形状由纳米颗粒状变为纳米棒

纳米棒的直径约为30~50 nm

纳米棒长约为200~300 nm。激发光谱和发射光谱分析表明

最大的激发带是位于254 nm的Eu

-O

电荷迁移带。最大发射峰位于611 nm

属于Eu

的特征发射。Y

: Eu

纳米发光粉的发光强度随着ω

的增加而增强。发光寿命分析表明Y

: Eu

纳米棒中Eu

的发光寿命为2.03 ms。在阴极射线发光真空装置中测得的I-V曲线表明Y

: Eu

纳米棒薄膜的启动电压仅1 300 V。同时

在2 000 V外加电压下可以清楚地观察到Y

: Eu

纳米棒的阴极射线发光为Eu

离子的特征红光。
