Abstract
PbS/CdS core/shell nanosheets were synthesized using the cation exchange method. A strong quantum confinement was observed in the PbS core due to a decrease in its thickness, indicated by a blue shift in photoluminescence. HRTEM revealed a flat atomic interface between PbS and CdS, and also the relationship between the energy-gap and the thickness in an extremely one dimensionally confined nanostructure. The photoluminescence lifetime of the core/shell nanosheets was significantly longer than the core-only nanosheets, indicating better surface passivation.
