Electron mobility in Alq3 determined via transient electroluminescence from single- and multilayer organic light-emitting diodes

Transient electroluminescence (EL) from singleand multilayer organic light-emitting diodes (OLEDs) was investigated by driving the devices with short, rectangular voltage pulses. The single-layer devices consist of indium-tin oxide (ITO) / tris(8-hydroxy-quinoline)aluminum (Alq3) / magnesium (Mg): silver (Ag), whereas the structure of the multilayer OLEDs… (More)
