Research Abstract

Crystal orientation of zinc oxide was efficiently controlled by the electrodeposition onto the modified ITO substrates, on which polymeric electrolyte adsorbed by layer-by-layer method. The zinc oxide crystals showed highly c-axis selectivity. The interaction between zinc atom on (001) face of zinc oxide crystal and sulfonic acid group on the surface of the LbL film would be responsible to the c-axis selective deposition. Thus obtained zinc oxide film exhibited higher transparency and photoluminescence efficiency than that of conventional electrodeposited zinc oxide films.
