纳米CdS/TAB的组装合成及表征

Synthesis, Assembly and Characterization of Nanoparticle Composite CdS/TAB

合成了纳米 Cd S/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 Cd S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

The nanoparticle composite CdS/TAB(dimethyldioctadecyl ammonium) is synthesized. It is investigated by IR spectroscopy, UV spectroscopy, X ray diffraction, TEM, AFM and SPS, which prove the existence of CdS nanocrystal 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.
