Light-Emitting Diodes: Highly Efficient Warm White Organic Light-Emitting Diodes by Triplet Exciton Conversion (Adv. Funct. Mater. 6/2013)
A novel all-phosphor, four-color, white organic lightemitting diode (WOLED) architecture is presented that utilizes molecular energy transfer or, specifically, triplet exciton down conversion within common organic layers in a cascaded emissive zone configuration. As reported by Yi-Lu Chang, Gregory D. Scholes, Zhenghong Lu, and co-workers on page 705, exceptional performance combinations of external quantum efficiency and color rendering index are achieved. This represents a significant step towards the realization of WOLEDs in solid-state lighting.
