Ultrahigh-radiance TTA-based OLED with 13 kA cm^-2 current injection.

ABSTRACT: Organic semiconductors have been widely utilized in displays, solar cells, detectors, and other fields due to their tunable optoelectronic properties and simple fabrication processes. However, fabricating organic electrically pumped lasers remains an unresolved challenge. The low mobility of organic molecules struggles to sustain the current injection required for electrically pumped lasing, and the free carriers and triplets generated under high current density also quench the gain characteristics. In device fabrication, high-conductivity electrodes and resonant cavities are inevitably accompanied by optical losses, which decrease the quality factor of the resonator and further elevate the threshold current density for electrical pumping. Here, we fabricated an organic light-emitting diod
