Effect of KCl on Crystal Morphology of Electrodepisited Cu₂O Thin Films

Abstract:

Different morphology of Cu₂O crystals were fabricated by electrochemical deposition using ITO and ITO/nano-TiO₂ as working electrode. The effect of different KCl concentrations on the microstructure and surface morphology of Cu₂O thin films were studied and the morphology controlled mechanism was also discussed. When the concentration of KCl was 7mmol/L, the shape of Cu₂O crystals evolved from dentrite to similar cube on the ITO matrix. When the concentration of KCl was 5mmol/L, the shape of Cu₂O crystals evolves from regular octahedron ({111} preferred orientation) to truncated cube ({100} preferred orientation) on the ITO/nano-TiO₂ matrix. The results also indicate that the substrates played a key role in the particle size control.
