Solution Processed, White Emitting Tandem Organic Light-Emitting Diodes with Inverted Device Architecture

Fully solution processed monochromatic and white‐light emitting tandem or multi‐photon polymer OLEDs with an inverted device architecture have been realized by employing WO3/PEDOT:PSS/ZnO/PEI charge carrier generation layers. The luminance of the sub‐OLEDs adds up in the stacked device indicating mu...

Zusammenfassung:Fully solution processed monochromatic and white‐light emitting tandem or multi‐photon polymer OLEDs with an inverted device architecture have been realized by employing WO3/PEDOT:PSS/ZnO/PEI charge carrier generation layers. The luminance of the sub‐OLEDs adds up in the stacked device indicating multi‐photon emission. The white OLEDs exhibit a CRI of 75.
