【摘要】 采用水相法在温和的条件下,通过调节反应物的浓度、控制反应平衡,制备了泪滴状和四臂的CdS纳米棒。探讨了前驱体对合成纳米棒的影响。透射电镜观察显示,其尺寸分布较均匀、长径比可在1~7之间调节;X射线衍射图证实所制备的CdS纳米棒具有六方堆积的纤锌矿结构。更多还原

【Abstract】 Teardrop-shaped and tetrapod-shaped CdS nanocrystals were prepared in aqueous solution under mild conditions through adjusting the concentration of reactants and the equilibrium reaction.Effects of the(precursors) on nanorods were further discussed.TEM images showed that nanocrystals had a narrow size distribution and a controllable aspect ratio(1~7) to some extent,and XRD measurement confirmed the wurtzite structure for the resulting CdS nanorods.更多还原
