| titleOfInvention | An organic electroluminescent device based on a fluorescent doped light-emitting layer |
| abstract | The invention relates to a device structure of an organic light-emitting diode (OLED), in particular to a high-efficiency fluorescence-doped organic electroluminescence device. The organic electroluminescent device prepared by the present invention is composed of a transparent substrate, a transparent anode, a hole transport layer, a first exciton blocking layer, a light emitting layer, a second exciton blocking layer, an electron transport layer, an electron injection layer and a metal cathode . The light-emitting layer is composed of host-guest doping, the host material is a small organic molecule with a small energy gap between the singlet excited state and the triplet excited state, and the guest material is a dye molecule with high fluorescence efficiency such as quinacridone derivatives. The external quantum efficiency of the device of the invention exceeds the theoretical limit efficiency of about 5% of the traditional fluorescent device, and can effectively improve the luminous efficiency of the fluorescent OLED device. The light-emitting device prepared by the invention has the advantages of high luminous brightness, low turn-on voltage, high efficiency, small efficiency roll-off, and the like. |
