Effect of KCl on Crystal Morphology of Electrodepisited Cu2O Thin Films

Abstract:

Article Preview

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.
