Abstract White organic light-emitting diodes (WOLEDs) have several desirable features, but their commercialization is hindered by the poor stability of blue light emitters and high production costs due to complicated device structures. Herein, we inv

Losses induced by triplet excitons are a major obstacle for electrically pumped organic lasers. Here, a combination of enhanced triplet-triplet upconversion and suppressed singlet-triplet annihilation is demonstrated as a route towards lasing in orga

Efficiency roll-off in organic light-emitting diodes under elevated current densities not only results in high power consumption but also device degradation. Here, the impact of polaroninduced quenching in efficiency roll-off was investigated and str

Though reducing non-emissive triplet excited-states using quenchers effectively improves organic semiconductor laser diode (OSLD) performance, existing quenchers are not suitable for devices. Here, the authors designed a solid-state triplet quencher
