ABSTRACT


Flexible Optoelectronic Technology Applied in Organic Light Emitting Diode (OLED)

Andre F. S. Guedes, Simone Tartari, Vilmar P. Guedes, Idaulo J. Cunha


The development of Flexible Optoelectronic applied in Organic Light Emitting Diode (OLED), using an flexible optically transparent substrate material and organic semiconductor materials, has been widely utilized by the electronic industry when producing new technological products. The OLED are the base Poly (3,4-ethylenedioxythiophene)-Poly(Styrenesulfonate), PEDOT:PSS, and Poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene], MEH-PPV, were deposited in Indium Tin Oxide, ITO, and characterized by UV-Visible Spectroscopy (UV-Vis), Optical Parameters (OP) and Scanning Electron Microscopy (SEM). The result obtained by UV-Vis has demonstrated that the PET/ITO/PEDOT:PSS/MEH-PPV layer does not have displacement of absorption for wavelengths greaters after spin-coating. Thus, the spectral irradiance of the OLED informed the luminance of 180 Cd/m2, and this result, compared with the standard Light Emitting Diode (LED), has indicated that the OLED has higher irradiance. After 2000 hours of electrical OLED tests, the appearance of nanoparticles visible for images by SEM, to the migration process of organic semiconductor materials, was present, then. Still, similar to the phenomenon of electromigration observed in connections and interconnections of microelectronic devices, the results have revealed a new mechanism of migration, which raises the passage of electric current in OLED.
