The electrochemical luminescence (ECL) device was investigated, which has similar structure to the dye-sensitized solar cell. The structure of the ECL cell in this experiment reliably induces a large amount of the oxidation around electrodes. The band gap of the ECL electrode is of 3.0 - 3.2 eV. Titanium dioxide (TiO₂) nanoparticle has following properties: a band gap of 3.4 eV, a lowpriced material, and 002 preferred orientation (Z-axis). Zinc Oxide (ZnO) nanorod is easy to grow in a vertical direction. In this paper, in order to determine material suitable for the ECL device, the properties of various materials for electrodes of ECL devices such as ZnO nanorod (ZnO-NR) and TiO₂ nanoparticle (TiO₂-NP) were compared. The threshold voltage of the light emission of the ZnONR was 2.0 V which is lower than 2.5 V of TiO₂-NP. In the other hand, the luminance of TiO₂-NP was 44.66 ㏅/㎡ and was higher than that of 34 ㏅/㎡ of ZnO-NR at the same applied voltage of 4 V. Based on the experimental results, we could conclude that TiO₂-NP is a more suitable electrode material in ECL device than the ZnO-NR.
