摘要
CdS/CdTe nanopencils were synthesized via anion exchange. The effect of the geometry on the carrier dynamics was investigated. Transient absorption measurements indicated that these factors did not affect the charge separation rate in CdS/CdTe nanopencils. The results provide important insight for designing heterostructured nanocrystals with efficient charge separation and integrated structures.
