摘要:Water-dispersible l-cysteine (l-cys)-capped cadmium sulfide (CdS) quantum dots (QDs) with a cubic structure and excellent crystallinity are synthesized by a one-pot method in aqueous solution, and the dots are subsequently used to grow QD-decorated zinc oxide (ZnO) nanorod (NR) heterostructures by the direct adsorption technique. Adjustment of the reaction time from 0.5 to 9 h allows tuning of the size of the synthesized CdS QDs from 2.30 to 2.78 nm. Quantum size effects lead to red shifting of the CdS QD absorption peak from 385 to 418 nm. The photoconversion efficiency (η) of CdS QD-sensitized ZnO NRs is enhanced by 250 % compared with that of unmodified ZnO NRs.
