摘要: 合成了纳米CdS/TAB(双十八烷基双甲基溴化铵)的复合物,通过IR,UV-Vis,XRD,TEM,AFM和SPS的研究,证实了CdS纳米晶的存在和核-壳结构的形成,并且证实了通过改变反应物的配比可以控制复合物的大小.EFM研究表明,这种有序的核-壳组装体可以产生电场超晶格.

关键词: CdS纳米晶, 核-壳结构, 电场超晶格

Abstract: The nanoparticle composite CdS/TAB(dimethyldioctadecyl ammonium) is synthesized. It is investigated by IRspectroscopy, UV spectroscopy, X-ray diffraction, TEM, AFM and SPS, which prove the existence of CdSnanocrystal and the formation of core shell structure. Also, the size of the composite can be controlled by altering the ratio.In the meantime, it is indicated by EFM that such orderly assembly substance can form electrostatic field superlattice.

Key words: CdS nanoparticles, Structure of core-shell, Electrostatic Field superlattice
