ORGANIC ELECTROLUMINESCENCE DEVICE
摘要:
An organic electroluminescence device having an anode, a cathode, and one or more of organic thin-film layers held between the cathode and the anode is characterized in that at least one of the organic thin-film layer is a multilayer of a layer containing a metal complex having an energy gap of above 2.8 eV and a host material layer. The electroluminescence device exhibits a high luminance and has an emission efficiency higher than conventional and a long life.
