In this work, a design of transparent conductive oxide less electrochemical luminescence (TCO-less ECL) cell has been proposed using a TiO2/Ti electrode. Ti films (~500 nm in thickness) are deposited on a glass substrate without Fluorinedoped SnO2 (FTO) by RF magnetron sputtering. The asprepared films were characterized by XRD, FE-SEM, XPS, and BET analyses. The as-fabricated ECL cell is composed of a FTO glass/Ru(II) complex/nanoporous TiO2/Ti/glass. The ECL efficiency of the TiO2/Ti-basd cell was ~265 cd/m2, much higher than the efficiency (135 cd/m2) of FTO-based cell. From the result, it can be found that the use of TiO2/Ti electrode significantly improves the ECL efficiency.
