| titleOfInvention | A kind of cadmium-doped perovskite light-emitting diode and preparation method thereof |
| abstract | The application discloses a cadmium-doped perovskite light-emitting diode and a preparation method thereof, and relates to the technical field of photoelectric device preparation, which includes: spin-coating an electron injection layer precursor on a cleaned conductive substrate to form an electron injection layer; Dissolving lead halide, halogen salt, organic passivator, and cadmium salt in an organic solvent to obtain a cadmium-doped perovskite precursor solution; spin-coating the perovskite precursor solution on the electron injection layer, and applying the spin-coating solution In the process, chlorobenzene anti-solvent is added dropwise, and the perovskite light emitting layer is formed by annealing; the hole injection layer precursor liquid is spin-coated on the perovskite light emitting layer to form the hole injection layer, and the hole injection layer is sequentially applied on the hole injection layer. The metal electrode modification layer and the metal electrode are vacuum thermally evaporated to obtain a cadmium-doped perovskite light-emitting diode. In the present application, the use of cadmium doping can effectively reduce the grain size, suppress the phenomenon of mixed halogen phase separation, and suppress the quenching of the surface fluorescence of the perovskite light-emitting layer, so that the cadmium-doped perovskite light-emitting diode has better spectral stability . |
