| Abstract;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 - .MU.s. 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. (author abst.) |
