• The quantum electroluminescence (EL) yield (ψEL) of a single-layer light-emitting diode (LED) based on a mixture of an oligothiophene (T5Ohex), an aromatic diamine (TPD) and bisphenol A polycarbonate (PC), and of a double-layer LED with a (TPD:PC) hole-transporting layer and an 8-hydroxyquinoline (Alq_3) electron-transporting layer, was measured as a function of electric field (F). The devices exhibit maximum ψEL(F) at F_<max> around 10^6 V・cm^<-1>. This behavior can be explained by the carrier motion-controlled Langevin recombination in the low-field region, and the Thomson-like recombination, controlled by the carrier capture, dominating the high-field regime.
