Chinese team report best solution-processed red LED

Their quantum dot LED, which was the subject of a paper in Nature today, exhibits colour-saturated deep-red emission, sub-bandgap turn-on at 1.7V, high external quantum efficiencies of up to 20.5 percent, low efficiency roll-off (up to 15.1 per cent of the external quantum efficiency at 100 mA cm-2), and a long operational lifetime of more than 100,000 hours at 100 cd m-2.

According to to the researchers, this makes making this device the best-performing solution-processed red LED so far, comparable to state-of-the-art vacuum-deposited organic LEDs.
