Description
Summary:The hole injection and emissive properties of top emission organic light emitting diodes with Nickel anode were investigated. The effect of oxygen plasma treatment on the Ni anodes was also investigated for enhancing the electrical properties of the devices. The device with Ni anode having an high work function shows better hole injection and emission characteristics than that with ITO. Oxygen plasma treatment of Ni anode induced further improvement of electrical properties and surface toughness. CIE coordinates of top emission device were different from bottom emission device. Ni anode induced the internal quantum efficiency of the device to be improved.
