  The present invention relates to organic light-emitting devices comprising (a) an anode, (i) a cathode, and (e) an emitting layer between the anode and cathode, comprising 2 to 40% by weight of a luminescent organometallic complex X having a difference of the singlet energy (ES1(X)) and the triplet energy (ET1(X)) of of ≤0.3 eV [Δ(ES1(X))−(ET1(X))≤0.3], 0.05 to 5.0% by weight of a fluorescent emitter Y and 55 to 97.95% by weight of a host compound(s), wherein the amount of the organometallic complex X, the fluorescent emitter Y and the host compound(s) adds up to a total of 100% by weight and the singlet energy of the luminescent organometallic complex X (ES1(X)) is greater than the singlet energy of the fluorescent emitter Y (ES1(Y)) [(ES1(X))>ES1(Y)]. By doping, for example, an emitting layer containing a luminescent organometallic complex having a small S1-T1 splitting, with a fluorescent emitter the emission decay time can significantly be shortened without sacrificing external quantum efficiency (EQE) because of very efficient energy transfer.

  本发明涉及有机发光器件，该器件包括(a)阳极，(i)阴极，和(e)阳极和阴极之间的发光层，该发光层包括2至40%(重量)的发光有机金属复合物X，其单线能(ES1(X))和三线能(ET1(X))之差≤0.3 eV [Δ(ES1(X))-(ET1(X))≤0.3]，0.05 至 5.0%(重量)的荧光发射体 Y 和 55 至 97.95%(重量)的宿主化合物，其中有机金属复合物 X、荧光发射体 Y 和宿主化合物的量相加的总重量为 100%(重量)，且发光有机金属复合物 X 的单子能 (ES1(X)) 大于荧光发射体 Y 的单子能 (ES1(Y))[ES1(X)>ES1(Y)]。例如，通过在含有发光有机金属复合物的发射层中掺入具有较小 S1-T1 分裂的荧光发射体，可以在不牺牲外部量子效率（EQE）的情况下显著缩短发射衰减时间，因为能量转移效率非常高。
