Long-range order enhance performance of patterned blue quantum dot light-emitting diodes.

ABSTRACT: Quantum dot light-emitting diodes show great potential for next-generation displays. Although film quantum dot light-emitting diodes have achieved or approached efficiency and stability standards for commercial applications, patterned quantum dot light-emitting diodes, particularly blue quantum dot light-emitting diodes, still face challenges in both efficiency and stability. Traditional patterning methods often lead to defects and disorder, causing non-radiative recombination and reduced performance. Here, we develop an aromatic-enhanced capillary bridge confinement strategy to achieve long-range ordered blue quantum dot microstructure arrays. These quantum dot arrays integrate into quantum dot light-emitting diodes achieve a peak external quantum efficiency of 24.1% and a peak luminance
