Voltage-invariant and efficient white emission from miscible polymer blend |
| 초록 |
We have demonstrated a simple and novel approach for generating stable and high efficient white light-emitting. By enhancing miscibility of blue and green-emitting polymer blend doped with red-emitting phosphorescent dye through introducing copolymer, typical problems of immiscible polymer system such as voltage-dependence and low efficiency were solved. The efficient energy transfer and charge trapping were observed in this system, so the relative intensity could be fine-tuned by varying the contents of three materials. The near pure white-light emission observed at wide range of voltage from 10V to 16V with high brightness[10295 cd/m2] and high luminance efficiency[8.34cd/A].
