Abstract

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.
