Abstract

DC current density-voltage and impedance spectroscopy studies have been performed on indium-tin-oxide(ITO)/para-sexiphenyl(6p)/aluminium organic electroluminescent device. The device exhibited a blue color emission, The turn-on voltage of the device is observed at 5V from the current density-voltage measurements. The impedance spectroscopy measurements show that a resonance frequency shift with applied DC bias is observed and a single semi-circle Cole-Cole plot is confirmed. The bias-dependent bulk resistance and bias-independent bulk capacitance is observed.
