P‐161: 89.3% Lifetime Elongation of Blue TTA‐OLED with Assistant Host. Issue 1 (May 2016) - Hsin, Meng-Hung
Abstract : Operation lifetime of a blue OLED exhibiting triplet‐triplet annihilation increased by 89.3% with the incorporation of 10% assistant host in the emitting layer, which increased diffusion length of singlet exciton, reduced the quenching of triplet exciton, and blocked the triplet pair diffusion.
