Estimating the term…
A composition suitable for use in an organic light-emitting layer (103) of an organic light-emitting device having an anode (101) and a cathode (105), the composition comprising a fluorescent light-emitting material, a first triplet-accepting material and a second triplet-accepting material that is different from the first triplet-accepting material. The fluorescent light-emitting material may be a repeat unit of a light-emitting polymer, and the first and second triplet-accepting materials may independently be repeat units of the light-emitting polymer or may be mixed with the fluorescent light-emitting material.
A composition comprising a light-emitting material, a first triplet-accepting material and a second triplet-accepting material that is different from the first triplet-accepting material.
(canceled)
An organic light-emitting device comprising an anode, a cathode and a light-emitting layer between the anode and the cathode wherein the light-emitting layer comprises a composition comprising a light-emitting material, a first triplet-accepting material and a second triplet-accepting material that is different from the first triplet-accepting material.
