Abstract

The electroluminescence (EL) of bilayer devices (ITO/Polymer/AIq₃/AI) made from two PPV derivatives (MN-PPV and MEH-PPV), respectively, and the influence of the organic layers' thickness on the characteristics of the device are investigated. Different spectra and variations are observed for different thicknesses of AIq₃ layer in this bilayer organic light-emitting diodes (LEDs) as increasing applied bias. Based on the energy level and field-assisted tunneling at the interface, we attributed these phenomena to electric field redistribution in the device and field-assisted charges being transported and tunneling through energy barrier at high electric field.
