Electrical properties of polymer light emitting diode using polyaniline-5% SiO2 nanocomposite as efficient hole-injection layer

Polyaniline-5% Fumed silica (PANI-5% SiO2) nanocomposite has been prepared to use as hole-injectionlayer in polymer light emitting diode (PLED) with structure ITO/PANI-5% SiO2/MEH-PPV/Al. The current densityvoltage(J-V) characteristic of the PLED has been investigated. The Fowler-Nordheim tunneling model has been usedto explain the obtained J-V data and the logarithmic plot of the J-V characteristic of the fabricated device showed apower law behavior (J∝ Vk+1) with two distinct regions.
