In this CrystEngComm Hot Article, Hongzheng Chen and colleagues synthesized uniform PbS nanocrystals using a surfactant-free electrodeposition method.
They investigated the effect of the concentration of Cl− ions, deposition time and applied deposition current in tuning the morphology of the crystals.
The authors believe the method could be extended to the shape-controlled synthesis of other semiconductor crystals, especially metal sulfides.
