| 摘 要： | 利用化学多元醇法合成Gd2O3：Tb^3＋纳米粒子，通过对NaOH的加入速率的控制，能将纳米粒子的直径从1-2nm能增大到4nm。利用透射电子显微镜，紫外分光光度计对Gd2O3：Tb^3＋纳米粒子的形貌和尺寸、发光进行表征分析。结果表明：分多次加入NaOH比一次性加入NaOH能获得更大尺寸的Gd2O3：Tb^3＋纳米粒子。

| Abstract: | Nanoparticles Gd2O3： Tb3＋ are synthesized by a polyol method. The size of nanoparticles obtained could be increased from 1-2 nm to 4nm in diameter by controlling the accelerating rate of NaOH. Nanopartieles Gd2O3 ： Tb3＋ are characterized by transmission electron microscope and speetrophotometer. The result shows that the size of Nanoparticles Gd2O3 ： Tb3＋ are bigger when NaOH is added progressively. |
