Light emitting composition and device |
| abstract |
A light-emitting layer comprising a phosphorescent material and a fluorescent light-emitting material of formula (I): wherein Ar¹ independently in each occurrence is a substituted or unsubstituted aryl or heteroaryl group and each R¹ is independently H or a substituent; and wherein a first phosphorescent light-emitting material is provided in the first light-emitting layer or in a second light-emitting layer adjacent to the first light-emitting layer. The phosphorescent material may be a metal complex. The photoluminescence peak may be less than 490 nm and the phosphorescent material may have a photoluminescence peak between 490 and 580 nm. A second phosphorescent material may also be applied, and the device may be a white light emitting device. The composition may be in a solvent, and the fluorescent material and the phosphorescent material may be in separate solutions with one deposited on the other, once the first solvent has evaporated. |
