Reduction of Efficiency Roll-Off and Extension of Device Lifetime Through a Double Sensitizer Structure-Controlling Triplet Diffusion

Student

Description:

This study introduces a double-sensitizer OLED architecture that combines a TADF sensitizer and a phosphorescent sensitizer in the emitting layer. The double-sensitized (TPDS) device improves performance by controlling triplet exciton diffusion, thereby enhancing stability and extending the operational lifetime by 53.5%. This approach advances the development of efficient deep-blue sensitizing OLEDs without requiring a planar n-type host.
