This approach involves trapping electron-transporting molecules within the host matrix to minimize exciton quenching and reduce the efficiency roll-off at high luminance.

(time to 50% initial brightness) of the devices compared to standard host-guest systems. 124694

High-energy blue excitons often lead to material degradation, particularly at the host-guest interface. 124694

The paper describes a multi-layer stack optimized for blue phosphorescent emitters. 4. Performance Results 124694

Experimental data confirms that the dual encapsulation method significantly extends the T50cap T sub 50
