Control of the Interface between Tris(8-quinolinolato) Aluminum and Aluminum Layers in an Organic Electroluminescent devices
摘要
Abstract
A bilayer Al 2O 3/Al is used as a cathode for organic electroluminescent devices. Six times higher electroluminescent efficiency is obtained without increasing the threshold voltage. The improvement is believed to be due to increasing injecting electron density, which improves the balanced injection of carriers, and declines the exciton-quenching and carrier-trapping centers that are intrinsic to the interface between of emitting layer and cathode.
