Blue ZnSeTe quantum dot light-emitting diodes with low efficiency roll-off enabled by an in situ hybridization of ZnMgO nanoparticles and amino alcohol molecules

In situ amino alcohol hybrid ZMO NPs have been developed, which not only reduces exciton quenching at the QDs/ETL interface, but also enhances electron injection. In the end, a peak EQE of 8.6% and an extremely low efficiency roll-off were achieved.
