Synthesis and characteristics of ZnS/CdS composite nanocrystals in block copolymer micelle

摘要

In hydroxylated poly(styrene-b-butadiene-b-styrene) (HO-SBS) micelle, ZnS/CdS composite nanocrystals were prepared by adding Cd~2+ ions and Zn~2+ ions to the system sequentially. The resulting composites were identified with elemental analysis, transmission electron microscopy, x-ray diffraction, surface photovoltage spectroscopy, and electric field induced surface photovoltage spectroscopy.
