Organic EL device with dual doping layers |
摘要 |
An organic light emitting device is positioned on an optically transmissive supporting substrate and includes a layer of ITO positioned on a planar surface of the substrate. A layer of hole transporting material with fluorescent dye molecules as fluorescent centers is supported on the layer of ITO, directly or with other layers, e.g. a hole injecting layer, therebetween. A layer of electron transporting material with fluorescent dye molecules as fluorescent centers is positioned on the hole transporting material and a layer of low work function metal is positioned on the layer of electron transporting material.
