摘要：

High-efficiency red emission is a prerequisite for full-color display applications of light-emitting diodes. The devices reported here-with stable external quantum efficiency up to 3.8 (photons/electron)-%-have a light-emitting layer consisting of a blend of a novel carbazole-based copolymer (see Figure) in MEHPPV, a more conventional conjugated polymer, as host.
