Popis:	We measured the electroluminescence (EL) generated from double-layer ITO/α-NPD/Alq3/Al diodes by applying large A.C. square voltages for understanding carrier behaviors. Two EL modes were identified in high and low frequency regions, relying on the D.C. component of the applied A.C. square voltages. This indicates that two different carrier behaviors are responsible for the EL emission from the double-layer EL diodes. Modeling the two EL modes, we showed the contribution of the D.C. component of applied A.C. square voltages to the two EL modes in terms of the interfacial Maxwell-Wagner charging.
