Electroluminescent device having a very thin emission layer |
摘要 |
An organic electroluminescent device comprises a pair of electrodes, and a layer structure provided between the pair of electrodes and including a charge transport layer capable of transporting electrons or holes and an emission layer comprising a major proportion of an organic material capable of emitting light on application of a voltage thereto via the pair of electrodes. The organic material undergoes concentration quenching and the emission layer has a thickness of 4 nm or below. The emission layer may be made of an electroluminescent organic material, which has a fluorescent lifetime shorter than an organic material present in the charge transport layer. <IMAGE> |
