Electrochemiluminescence (ECL) displays have attracted significant attention because of their economic and processing advantages. However, despite these advantages, low luminous efficiency presents difficulties in their commercialization. To overcome this issue, a catalytic-activity-driven approach using Pt nanoparticles (NPs) anchored on CuO nanorod (NR) electrodes (PCNEs) is introduced. The Pt NPs facilitated the electron-transfer processes in the ECL reaction, and their catalytic activity was maximized by employing CuO NRs as nano-supports, offering more catalytic sites for Pt NPs. The optimized PCNE-based ECL display enabled extremely low-voltage operation of multicolor ECL displays, along with enhanced luminance compared with bare fluorine-doped tin oxide (FTO)-based ECL displays. ECL displays utilizing optimized PCNEs provide an effective template for next-generation ECL-material-based display applications.
