The advantages of ion-gel-based electrochemiluminescence (ECL) displays over organic light emitting diode (OLED) displays are their simple structure, low processing cost, and insensitivity to moisture. Despite these advantages, ion-gel-based ECL displays suffer from low light-emission efficiencies. Therefore, in this study, catalytic Au nanoparticles (NPs) were applied in ECL displays to improve their light-emission efficiency. Furthermore, the catalytic activity of the Au NPs was maximized by applying three dimensional ZnO nanorods (NRs) on the bottom electrode. Whereas the conventional ion-gel-based red (R), green (G), and blue (B) ECL devices with indium tin oxide (ITO) electrodes are driven at 3.0 V_PP, the R, G, and B ECL devices with Au NPs can be driven at 2.0, 1.8, and 1.9 V_PP, respectively, because the activation properties of the catalysts were maximized by incorporating ZnO NRs in the electrode. Thus, this study demonstrates that Au NPs can be applied as electrochemical catalysts in ECL devices. Furthermore, by employing the ZnO NRs, ECL devices that can be driven by extremely low voltages were successfully fabricated with a simple structure, using a simple process.

与有机发光二极管（OLED）显示器相比，基于离子凝胶的电化学发光（ECL）显示器的优势在于其结构简单，处理成本低以及对湿气不敏感。尽管有这些优点，基于离子凝胶的ECL显示器的发光效率仍然很低。因此，在这项研究中，催化金Au纳米颗粒（NPs）用于ECL显示器以提高其发光效率。此外，通过在底部电极上施加三维ZnO纳米棒（NRs），可以使Au NPs的催化活性最大化。常规的具有铟锡氧化物（ITO）电极的基于离子凝胶的红色（R），绿色（G）和蓝色（B）ECL器件是在3.0 V _PP下驱动的，而R，G和B ECL器件具有3.0 V _PP的驱动力。可以在2.0、1.8和1.9 V _PP下驱动Au NP分别是因为通过在电极中加入ZnO NRs可以使催化剂的活化性能最大化。因此，该研究表明Au NPs可以用作ECL装置中的电化学催化剂。此外，通过使用ZnO NR，可以使用简单的工艺，简单的工艺成功地制造出可以由极低电压驱动的ECL器件。
