Abstract

Abstract : Flexible quantum dotlight‐emitting diodes (QLEDs) are demonstrated by using hot‐pressing AgNWs as the transparent conductive electrode and EGaIn as the back electrode. Both AgNWs and EGaIn are printable, and thus the whole device can be fabricated via vacuum‐free processes. The hot‐pressing AgNWs electrode exhibits excellent physical characteristics such as high transparency of 96.7% in the visible spectral region, and low sheet resistance of 28 Ω/sq. With the AgNWs and EGaIn, vacuum‐free‐fabricated QLEDs are successfully achieved with efficiency 13.2cd/A. Because of the elimination of the costly vacuum processes, the proposed fabrication processes are low cost and allow rapid fabrication of flexible QLEDs with high performance.
