Abstract:ZnO films with different morphologies were deposited on the ITO-coated glass substrate from zinc nitrate aqueous solution at 65 C by a seed-layer assisted electrochemical deposition route. The seed layers were pre-deposited galvanostatically at different current densities (isl) ranging from –1.30 to –3.0 mA/cm2, and the subsequent ZnO films had been done using the potentiostatic technique at the cathode potential of –1.0 V. Densities of nucleation centers in the seed layers varied with increasing the current density, and the ZnO films on them showed variable morphologies and optical properties. The uniform and compact nanocrystalline ZnO film with (002) preferential orientation was obtained on seed layer that was deposited under the current density (isl) of –1.68 mA/cm2, which exhibited good optical performances.
