摘要：

By using the unique properties of the efficient orange-red phosphorescent osmium complex in combination with an efficient blue phosphorescent Iridium complex, efficient white organic light-emitting devices with forward viewing efficiencies up to (17% photon/electron, 36 cd/A, 28 lm/W) and white organic light-emitting devices with color stability vs. brightness can be implemented. Results show that the osmium complex is a multi-functional material that not only has high emission efficiency, but also possesses the effective hole trapping capability, which is useful for balancing hole/electron transport and controlling the emission zones when doped at appropriate locations of the device.
