We report on fabrication and characterization of an organic light emitting diode by incorporating a pure DNA as electron blocking layer. As emission layer a thin film of phosphorescent Ir(ppy)(3) luminophore, embedded in the poly(N-vinylcarbazole) (PVK)/2-(4-tert-butylphenyl)-5-(4-biphenylyl)-1,3,4-oxadiazole (PBD) is used. The BioLED shows a good stability and its luminance efficiency vs current density is improved by ca 40% in comparison with the case without EBL. (C) 2014 Published by Elsevier B.V.
