摘要：
A tandem organic electroluminescent device includes an anode and a cathode. The device also includes a plurality of organic electroluminescent units disposed between the anode and the cathode, wherein each of the organic electroluminescent units includes one or more organic layers including at least a light-emitting layer and an associated light-emitting junction, connecting unit disposed between adjacent organic electroluminescent units, and wherein at least two of the neighboring light-emitting junctions are separated by a distance of less than 90 nanometers.
