| titleOfInvention | Blue light perovskite quantum dot films and electroluminescent diodes and their preparation |
| abstract | The invention relates to the technical fields of nanotechnology and light-emitting display, and provides a blue-light perovskite quantum dot film and an electroluminescent diode and their preparation. Blue-emitting perovskite quantum dots with high fluorescence yield (PLQY)>90% were obtained by chemical synthesis of bromide-rich ion solution, and organic ligand quantum dots PQD‑1 and inorganic ligand quantum dots PQD‑ were obtained by ligand exchange process 2, then prepare a three-layer structure quantum dot film composed of PQD-1 layer, zinc chloride passivation layer, and PQD-2 layer, and finally combine with transparent conductive oxide anode TOC, hole transport layer material HTL, and electron transport layer material ETL and metal cathode CL to form an electroluminescent diode. The electroluminescent diode of the present invention significantly reduces the binding energy of excitons to suppress Auger recombination, and reduces the electron injection rate to reach a balance with the hole injection rate; the electroluminescent diode of the present invention has high current efficiency and external quantum efficiency, and good stability , Long working life. |
