The silicon-locked host enables highly efficient blue emission with minimized non-radiative loss.
(time to 50% initial brightness) of the devices compared to standard host-guest systems. 124694
The paper describes a multi-layer stack optimized for blue phosphorescent emitters. 4. Performance Results 124694
High-energy blue excitons often lead to material degradation, particularly at the host-guest interface. 124694
The host material incorporates a rigid silicon-locked framework to prevent molecular rotation and improve heat resistance.
This approach involves trapping electron-transporting molecules within the host matrix to minimize exciton quenching and reduce the efficiency roll-off at high luminance.
Blue OLEDs are critical for full-color displays but typically suffer from shorter lifespans and lower efficiency compared to their red and green counterparts.
