Abstract

Highly efficient and stable, red phosphorescent organic light-emitting diodes (OLEDs) are demonstrated using platinum complexes. The host/dopant combination is a crucial factor in obtaining high efficiency and stability. The OLEDs exhibit a maximum external quantum efficiency of about 20% and an expected half-life of about 10 000 h with an initial luminance of 1000 cd m -2.
