Current-voltage, impendance, absorption and emission measurements have been carried out with ITO/LP/metal and IZO/LP/metal (LP – Luminescent Polymers) with the objective to compare the performance of IZO with that of ITO. We use as active LP layers in the electroluminescent devices two different polymeric films: poly[2-methoxy, 5-(2-ethylhexoxy)-1,4-phenylene vinylene], and a blend of composed by two derivatives of polyfluorene, (poly(2,7-9,9'-di-n-hexilfluorene) and poly(9,9–di-hexilfluorenediilvynilene-1,4-phenylenevynilene). The deposited thin films, by spin-coating process, were optically characterized before to build the devices. An investigation of the electrical properties of IZO shows that it can be used as transparent anode to replace the commonly used ITO. In addition, we developed a detail study on current-voltage characteristics and real and imaginary part of the impedance. Fitting of the experimental results were obtained by the Random-Free Barrier model that assumes, based on the disordered structure of the polymer film, a random distribution of energetic barriers, for carriers, that should be surpassed by hopping or by tunneling activated by phonons.
