Patent ID: 11851343

Abstract:
A preparation method for a metal oxide nanoparticle film and an electrical component, comprising: preparing a halogen ligand-containing metal oxide nanoparticle by performing heated alcoholysis of a metal halide in an organic alcohol; and employing a solution method on the halogen ligand-containing metal oxide nanoparticle to prepare a halogen ligand-containing metal oxide nanoparticle film. The halogen ligand-containing metal oxide nanoparticle is produced by means of performing the alcoholysis of the metal halide, then the halogen ligand-containing metal oxide nanoparticle is prepared into the film, and then a halogen is utilized once again in a passivation processing of the film, this not only further reduces defects on the surface of the metal oxide nanoparticle, but also further improves charge transfer between the metal oxide nanoparticle and an active functional layer and increases transfer efficiency, thus increasing component efficiency.
