| titleOfInvention | A phosphorescence-sensitized fluorescent organic light-emitting diode |
| abstract | The invention belongs to the field of organic light-emitting diodes, and discloses a phosphorescence-sensitized fluorescent organic light-emitting diode. The phosphorescence-sensitized fluorescent organic light-emitting diode comprises a substrate, an anode, a hole injection layer, a hole transport layer, an electron blocking layer, a light-emitting layer, an electron transport layer, an electron injection layer and a cathode that are stacked in sequence; the light-emitting layer is composed of A phosphorescent sensitizer and a fluorescent guest-doped host light-emitting material are formed. The device involved in the present invention adopts the method of co-doping phosphorescent material and fluorescent material in the host, and realizes 100% exciton utilization rate, so that the prepared OLEDs have the characteristics of high efficiency and low roll-off. |
