Ultrafast charge-transfer (CT) dynamics has been demonstrated in CdS quantum dot (QD)–4′,5′-dibromofluorescein (DBF) composite materials, which form a strong CT complex in the ground state. Charge separation in the CdS–DBF composite was found to take place in three different pathways, by transferrin...
