|Title||Investigation of the effect of different dyes on organic light emitting diode properties|
In this article we report electroluminescence (EL) from double and single layer thin film devices comprising poly(N-vinylcarbazole) (PVK) films doped with various new emitter molecules (dyes). The structure of the single layer device is doped PVK sandwiched between indium tin oxide (ITO) and aluminum (Al) layers as anode and cathode, respectively. We have used 2% concentration of Rhodamine 6G, carbocyanine, 1,2,4 oxadiazole, and fluroscein dyes. The double layer device has the structure ITO/PVK/8-hydroxyquinoline aluminum (Alq 3)/Al. We have studied the IV characteristics as well as the variations of the EL with voltage and current of these devices. : poly(9-vinylcarbazole) (PVK) . PVK ITO Al .
