| titleOfInvention | A kind of planar heterojunction organic light-emitting diode and its preparation method |
| abstract | The invention belongs to the technical field of organic photoelectric materials, and discloses a planar heterojunction organic light emitting diode and a preparation method thereof. The light emitting diode includes a substrate, an anode, a P-type organic semiconductor layer, an N-type organic semiconductor layer and a cathode stacked in sequence. The P-type organic semiconductor layer is made of an organic semiconductor material that can better conduct holes, and the N-type organic semiconductor layer is made of an organic semiconductor material that can better conduct electrons. The light color of the light-emitting diode of the present invention comes from the interaction of PN heterojunction, and the light-emitting spectrum is different from that of a single P-type or N-type semiconductor, and the light-emitting diode of the present invention is made of P-type materials and N-type materials stacked on each other. Composed in this way, there is no light-emitting layer of traditional organic light-emitting diodes, and it has a low driving voltage and high luminous efficiency, and has a good application prospect. |
