摘要
The lifetime of green phosphorescent light-emitting diodes was improved by using a graded doping structure in light-emitting layer. A green device with high doping concentration at the hole transport layer and light-emitting layer interface showed longer lifetime than a conventional device with uniform doping concentration for the whole light-emitting layer by more than 60%.
