| titleOfInvention | A red-light organic electroluminescence device with double light-emitting layers and its preparation method |
| abstract | The invention relates to a double-emitting layer red light organic electroluminescent device and a preparation method thereof. The structure of the light-emitting device is as follows from bottom to top: a transparent substrate, a transparent conductive anode, an anode modification layer, a hole transport layer, and an excitation layer. Sub-blocking layer, light emitting layer, electron transport layer, cathode modification layer, cathode; red light emitting layer is composed of light emitting layer I and light emitting layer II, the main materials of light emitting layer I and light emitting layer II are bipolar type and electron type respectively, The red phosphorescent guest material is doped into the host material of two different conductivity types to form a double-layer light-emitting layer. In the present invention, the light-emitting layer I with bipolar materials as the main body serves as the main light-emitting area for exciton radiative recombination, and the light-emitting layer II with electronic materials as the main body can reduce the gap between different conductivity types of materials due to the high hole mobility. Accumulation, broaden the luminous range, reduce exciton quenching and non-radiative recombination, and have the advantages of high luminous intensity, high luminous efficiency, and good color purity. |
