Zusammenfassung:In hydroxylated poly(styrene-b-butadiene-b-styrene) (HO-SBS) micelle, a series of CdS nanocrystals with different sizes have been prepared by means of simply repeating the synthesis procedure for a definite number of cycles. A variety of techniques including element analysis, infrared spectroscopy (IR), transmission electron microscopy (TEM), UV−visible spectroscopy, surface photovoltage spectroscopy (SPS), and electric field induced surface photovoltage spectroscopy (EFISPS) had been used for the characterization of the resulting CdS/HO-SBS nanocomposites. A reasonable energy band model was supposed to describe the electron process in the nanocomposites.
