In hydroxylated poly(styrene-b-butadiene-b-styrene) (HO - SBS) micelle, ZnS
/Cd composite nanocrystals were prepared by adding Cd2+ ions and Zn2+ ions
to the system sequentially. The resulting composites were identified with e
lemental analysis, transmission electron microscopy, x-ray diffraction, sur
face photovoltage spectroscopy, and electric field induced surface photovol
tage spectroscopy.
