The performance of polymer light emitting diode (PLED) strongly depends on materials, fabrication and the structure of the device. Polymer light-emitting diodes typically consists of emitting layer(s) sandwiched between a cathode and an anode. In our study indium tin oxide (ITO) is used as anode, the polymer blend as emitting layer and metals such as aluminum, silver as cathodes. Investigation in this area is focused to fully understand and develop the method of fabrication of PLEDs using the available resources and to understand the effect of variation of blend ratios of polyfluorene polymers (TFB: 9, 9'-dioctylfluorene-co-N-(4-butylphenyl) diphenylamine and F8BT: poly (9, 9'dioctylfluorene- co-benzothiadiazole)), different cathodes, addition of buffer layer (calcium acetylacetonate [Ca (acac)z]) on the built devices.
