LIGHT EMITTING COMPOSITION AND DEVICE |
| 摘要 |
An organic light-emitting device comprising an anode; a cathode; and a first light- emitting layer between the anode and the cathode, wherein the first light-emitting layer comprises 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. |
