SINGLET HARVESTING WITH ORGANIC MOLECULES FOR OPTOELECTRONIC DEVICES

摘要

The invention relates to a composition having an organic emitter molecule which has a ?E(S1-T1) value between the lowermost excited singlet state (S1) and the triplet state (?1) therebelow 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.
