“…The thermionic injection is considered an additional type of charge injection as expressed in eq. (3), 13) in which A is the Richardson constant, ' c the height of the potential barrier and T the temperature. The electric field is considered a function of applied voltage and built-in voltage (V bi ) and is expressed in eq.…”

We investigated the transient electroluminescence (EL) and transient current (TC) of organic light-emitting diodes under a trapezoid electric pulse at a repetition rate of 1 kHz by changing the transient time of the pulse from ∼ ns to ∼ µs. Our data shows that the change in the transient time of the pulse not only affects the delay time and rise time of transient EL, but also changes the temporal evolution of TC. In addition, we studied the charge accumulation in the interfacial layer of organic films with different heterostructures, particularly the EL spike from a pulsed device with 1,4-Bis[2-[4-[N,N-di( p-tolyl)amino]phenyl]vinyl]benzene as a light-emitting layer at switch-off. The dynamic behavior of TC was further analyzed by computational approaches.

In this work we investigate the operation mechanism of hybrid organic/inorganic quantum dot light emitting devices (QD-LEDs). We employ a numerical method previously established to describe current-voltage characteristics, spatial distributions of charge, electric field, and recombination rate in organic light emitting devices (OLEDs). The numerical solution of the continuity and Poisson equations have been extended to treat internal organic/Quantum Dot (QD) interfaces, recombination processes in the polymer matrix and in the QDs, and the charge acquired by the QDs. The contact boundary condition is taken to be Schottky contact boundary condition. Also, we consider the exciton formation and diffusion processes. The simulation results trend and experimental data are in good agreement.
