摘要 |
The invention relates to a composition comprising an organic emitter molecule, this molecule having a DeltaE(S1-T1) value between the lowermost excited singlet state (S1) and the triplet state beneath it (T1) of less than 2500 cm-1, and an optically inert atom or molecule for reducing the inter-system crossing time constant of the organic molecule to less than 10-6 s. |
