We report Zinc oxide (ZnO) nanorods synthesis and electrochemical luminescence (ECL) cell fabrication. The ECL cell was fabricated using the electrode of ZnO nanorods and Ru(II) complex (Ru(bpy)3 2+ ) as a luminescence materials. The fabricated ECL cell is composed of F-doped SnO2 (FTO) glass/ Ru(II)/ZnO nanorods/FTO glass. The highest intensity of the emitting light was obtained at the wavelength of ∼620 nm which corresponds to dark-orange color. At a bias voltage of 3V, the measured ECL

At a bias voltage of 3.5V, the use of ZnO nanorods increases ECL intensities by about 3 times compared to the typical ECL cell without the use of ZnO nanorods.
