Abstract
A fluorescent infrared emitting composition comprising a mixture of a first material and a second material wherein the first material is a fluorescent infrared material and the second material is a fluorescent material having a higher photoluminescent quantum yield (PLQY) and shorter peak wavelength than the infrared emitting material. The composition may be used as the light-emitting layer of an organic light-emitting device.
