摘要：

Operational stabilities of high-efficiency green and red electrophosphorescent bottom-emission devices with various emitting dopants have been studied. Operational lifetimes of 10,000 h or more, operated at an initial brightness of 600 and 300 cd/m(2) for green and red, respectively, are reported. Operational stabilities of top-emission electrophosphorescent devices and electrophosphorescent devices built on barrier-coated plastic substrates have also been studied and show lifetimes >5000 and >2000 h, respectively, under display level brightness conditions.
