Abstract

Liquid metal eutectic gallium-indium (EGaIn) is applied as the top electrodes for QLEDs to solve the challenge of vacuum-free-processed devices in this study. With the patterned EGaIn electrodes, a highly efficient green QLED is demonstrated with a peak current efficiency over 80 cd/A, a peak EQE over 18 %, and a maximum power efficiency close to 50 lm/W, which is among state-of-the-art QLEDs performance data. The vacuum-free-deposited EGaIn electrodes developed in this work can eliminate the vacuum processes, thus significantly reducing the production cost, allowing for fast fabrication of devices.
