The optical and electrical properties of polymer light emitting diodes based on poly [2-(3-thienyl) ethanol butoxy carbonyl-methyl urethane] as emitting layer have been studied. The diode structures have been made by utilizing indium tin oxide coated glass as an anode and aluminum as a cathode. Polyaniline and tris(8-hydroxy-quinolino) aluminum have been employed as hole and electron transport layers, respectively. Enhanced electroluminescence (EL) near the turn-on voltage has been observed on addition of 4-dicyanomethylene-2-methyl-6-(p-dimethylaminostyryl)-4H-pyran dye. On the basis of current–voltage, luminance–voltage, capacitance–voltage, and impedance measurements, an attempt has been made to understand the mechanism of EL emission in these polymeric light emitting diodes. © 2001 American Institute of Physics.
