Quantum dot (QD) light-emitting diodes (LEDs) are ideal for large-panel displays because of their excellent efficiency, colour purity, reliability and cost-effective fabrication 1 – 4 . Intensive efforts have produced red-, green- and blue-emitting QD-LEDs with efficiencies of 20.5 per cent 4 , 21.0...
