Abstract: |
The invention consists of transparent base plate, anode layer and organic functional layer. The light emitting layer in organic functional layer comprises main body material, blue phosphorescence fluorochrome. The doping concentration of phosphorescence fluorochrome is: 1-20wt%. The doping concentration of fluorochrome is 0.05-1wt%. Due to increasing the utilization of fluorochrome, high efficiency red fluorescence is obtained. Combining blue fluorescence emitted from fluorochrome the high efficiency phosphor photo- activation fluorescence white light device is obtained. |
