Visible light-induced hole transfer in single-nanoplate Cu1.81S–CdS heterostructures

The carrier dynamics of Cu 1.81 S nanoplates, Cu 1.81 S-CdS heteronanoplates and CdS nanoplates were investigated, and the results indicate that photogenerated holes may be transferred from the CdS phase to the Cu 1.81 S phase under 400 nm excitation.
