A novel candle light-style OLED with a record low colour temperature

Abstract

The possibility of using a single light-emitting layer consisting of newly synthesized fluorescent small organic molecules of D–A–π–A type incorporated into a conductive matrix together with an electron conductive Alq₃ layer in order to form radiation in candle light-style OLEDs was shown for the first time. A record low color temperature of 1722 K OLED radiation was achieved, which is by 80 K lower than that of the best devices reported previously.
