| 摘要 |
A stacked electro-optically active organic diode has an anode electrode (102), a cathode electrode (162), a first electro-optically active organic layer (110) arranged between the electrodes (102, 162), and a second electro-optically active organic layer (130) arranged between said first active organic layer (110) and said cathode (162). A low electron affinity layer (120) is arranged between the first electro-optically active organic layer (110) and the second electro-optically active organic layer (130), and is formed of a first transparent inorganic semi-conductor material. A high electron affinity layer (121) is arranged between said second electro-optically active organic layer (130) and the low electron affinity layer (120), and is formed of a second transparent inorganic semiconductor material, wherein said second transparent inorganic semiconductor material has a higher electron affinity than said first inorganic semiconductor material. The low and high affinity layers (120, 121) constitute a connection layer of only two semiconductor (sub-)layers which allow for transparent, thick layers, and as a result the diode can be both efficient and reliable.
