Though organic light-emitting diodes are highly desirable for display and lighting applications, efficiency roll-off at high current densities limits its applicability. Here, the authors report a triplet scavenging strategy for improved triplet excit

The simultaneous achievement of efficient photoluminescence quantum yield (PLQY) and horizontal orientation of a transition dipole moment (TDM) in thermally-activated delayed fluorescence (TADF) emitters remain a significant challenge toward the real

Continuous-wave (CW) lasing is still difficult to realize in organic laser dyes, one reason being the thermal degradation caused by intense photoexcitation. A decrease in laser threshold suppresses...

Large external quantum efficiency rolloff at high current densities in organic light-emitting diodes (OLEDs) is frequently caused by the quenching of radiative singlet excitons by long-lived triplet excitons [singlet–triplet annihilation (STA)]. In

Triplet exciton accumulation and singlet-triplet annihilation (STA) are major issues, which makes continuous-wave (CW) operation difficult, in organic lasers. We synthesized an organic laser dye, 2,6-dicyano-1,1-diphenyl-λ5σ4-phosphinine (DCNP), ha
