摘要：
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 (Rufbpyh2*) as a luminescence materials. The fabricated ECL cell is composed of F-doped SnÛ2 FTO glass/ Ru(ID/ZnO nanorods/FTO glass. The highest intensity of the emitting light was obtained at the wavelength of nm which corresponds to dark-orange color. At a bias voltage of 3V, the measured ECL efficiencies were 5 cd/m2 for cell without ZnO nanorod, 145 cd/m2 for ZnO nanorods̃5pm, 208 cd/m2 for ZnO nanorods-8iim and 275 cd/m 2 for ZnO nanorods-lOym, respectively. 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.
