Electroluminescent devices with low work function anode |
摘要 |
Disclosed are organic electroluminescent devices employing materials of a low reduction potential in a layer functioning hole-injection. The organic electroluminescent devices may employ an anode material having a relatively low work function. Aluminum may be used in anode. During the operation, the organic electroluminescent devices may form a virtual electrode in their internal area, which enhances injection of carriers from a nearby electrode. Use of aluminum in the anode helps construction of cathode-emission organic electroluminescent devices.
