Color variable bipolar/AC light-emitting devices |
摘要 |
Color-variable light-emitting devices which are capable of generating two independent colors, even at room temperature. The devices comprise a layer of at least one active electroluminescent polymer. This electroluminescent polymer may be accompanied by one or two redox-mediating polymer layers. The redox polymer layer(s) modify the charge injection and transport properties such that the device may be operated under both forward and reverse bias.
