Abstract
The effect of thermal conversion process of PPV, insertion of poly (N-vinyl carbazole), PVK layer under PPV, and insertion of PBD-polymer matrix as electron transport/hole blocking layer above PPV on the EL device were studied. Luminance intensity of ITO/PVK/PPV/Mg and ITO/PPV/polymer matrix-PBD/Mg EL devices were dependent on the thermal conversion temperature of PPV emitting layer in the order 140 degrees C > 180 degrees C > 220 degrees C > 260 degrees C. Luminance intensity was also dependent on thickness of PVK layer in the ITO/PVK/PPV/Mg EL device. In the ITO/PPV/PBD-polymer matrix/Mg EL device, the intensity of EL device was highest with polystyrene as matrix
