摘要：
The present invention relates to a an organic electroluminescent device comprising a light-emitting layer B comprising a host material HB, a first thermally activated delayed fluorescence (TADF) material EB, and a second TADF material SB, wherein EB transfers energy to SB and SB emits TADF with an emission maximum between 420 and 500 nm.
