【摘要】 近几年,富勒烯C₆₀新的一维纳米聚集态结构,如C₆₀纳米棒、纳米线、纳米管等成为热点研究课题之一。富勒烯纳米棒既保持了富勒烯分子的结构和性质,作为新的聚集态结构又具有准一维纳米材料的特点。本文利用液-液界面析出法成功制备了在位制备了棒状C60和不同粒径CdSe/Cd S/ZnS量子点的复合结构,并研究了不同粒径CdSe量子点对C₆₀纳米棒的修饰作用,以及CdSe/CdS/ZnS量子点对C60棒表面电势的影响。结果表明,CdSe/CdS/ZnS量子点使原本负表面电势的C60棒变为正表面电势。时间分辨荧光光谱表明CdSe/CdS/ZnS量子点的粒径越小,和C₆₀棒之间的能量转移效率越高。更多还原

【Abstract】 In recent years, new aggregation of fullerene C₆₀ one-dimensional structure, such as C₆₀ nanorods, nanowires, nanotubes have become one of the hot research topics. In this paper, the CdSe/CdS/ZnS/C₆₀ nanorods were successfully prepared by liquid-liquid interface precipitation method. The modification of CdSe/CdS/ZnS quantum dots on C₆₀ nanorods and its effect on the surface potential were studied. The results showed that the negative surface potential of C₆₀ nanorod changed to positive surface potential under the help of Cd Se/Cd S/Zn S quantum dots.更多还原
