| Abstract: | Organic light emitting devices (OLED) based on tris(8-hydroxyquinoline) aluminum (Alq 3) and Indium Tin Oxide(ITO) transparent anode were fabricated.Photoluminescent(PL) spectra and current-voltage data were obtained.The threshold voltage of the devices was about 12V. Studies reveal that the carrier injection was consistent with the tunneling theory.Degradation of current with time at a given external voltage was measured and the reason was analyzed. |
