The use of 2-(4-biphenyl)-5-(4-butylphenyl)-1,3,4-oxadiazole (PBD) as an anode buffer layer in organic light-emitting devices (OLEDs) with a configuration of indum tin oxide/α-naphtylphenyliphenyl diamine/8-hydroxyquinoline aluminum/LiF/Al has been studied. With PBD buffer layer several angstroms thickness, the current efficiency increased and the stability of the device was improved. The results...
Organic light-emitting diodes (OLEDs) with a nanostructured TiO 2 layer at the interface between indium tin oxide and a-naphtylphenyliphenyl diamine layers were fabricated using a vacuum evaporation method. The nanostructured TiO 2 layer was achieved by the Sol-Gel method. Compared to the different thickness of the buffer layer, the OLEDs with the 6 nm buffer layer showed the highest...
