Abstract

Efficient, pure red-emitting polymer light-emitting diodes have been prepared by doping blue-emitting conjugated polymers with europium β-diketonate complexes (see Figure). The pure red emission is required for full color displays, while the blends are also expected to be useful as emitters in photonic crystals due to their narrow monochromaticity (see also cover).
