| 英文摘要 | The effect of thermal annealing on electroluminescence of polyfluorene-based single white emissive polymer is demonstrated. Both color purity and light-emitting efficiency of the devices are enhanced via thermal annealing. It is found that thermal annealing can induce the formation of crystalline polyfluorene phase that acts as an efficient blue fluorescent dopant for enhancing blue emission and hence color purity of the white light. Most importantly, the hole and electron transport is balanced after thermal annealing that favors improving the light-emitting efficiency. A light-emitting efficiency of 10 cd/A is achieved after thermal annealing, about 30% increase compared to the as-produced device. |
