摘要
We report on a highly efficient phosphorescent organic lght-emitting devices achieved by introducing nanoscale double interfacial layers, The double interfacial layers play multiple roles in the enhancement of devices performance: increasing electron injection, hole-blocking, and preventing luminescence quenching at the electrode surface. As an experimental result, current efficiency was improved to 240%, yielding a peak brightness over 40,000 cd/m(2) and peak efficiency over 60 cd/A.
