The present invention relates to a light-emitting layer B comprising a first emitter compound (a) having a non-exited state S0(a), a first excited singlet state S1(a) and a first excited triplet state T1(a); a second emitter compound (b) having a non-exited state S0(b), a first excited singlet state S1(b) and a first excited triplet state T1(b), wherein the energy level of S1(a) is higher than that of S1(b), the energy level of S1(b) is higher than that of T1(b) and wherein the rate of reverse intersystem crossing from T1(a) to S1(a) is higher than the rate of excitation energy transfer from S1(a) to S1(b) and/or the rate of excitation energy transfer from T1(a) to T1(b), and/or wherein the energy level of T1(b) is higher than that of T1(a). Further, the present invention also refers to an opto-electronic device comprising such light-emitting layer B and use thereof.
