Solution-processed and high-performance light-emitting diodes based on quantum dots

Open Access Open Access

Abstract

We report a solution-processed multi-layer QLED with high EQE up to 20.5%, low efficiency roll-off (>15% of EQE at 100 mA cm−2), and a long operational lifetime of over 100,000 hours at 100 cd m−2.
