HXMoO3 nanoparticle solution, preparation method and application thereof, and quantum dot light emitting diode

The invention belongs to the technical field of semiconductor display and illumination materials, and particularly relates to an HXMoO3 nanoparticle solution, a preparation method and application thereof, and a quantum dot light emitting diode. According to the preparation method of the HXMoO3 nano-particle solution, on the basis of the oxidation reaction of molybdenum powder and hydrogen peroxide, under the action of an alcohol solvent, the reaction system is subjected to the purification process of filtering, drying by distillation, dispersing and centrifuging, so that the molybdenum powder and hydrogen peroxide left in the oxidation reaction can be eliminated, and the purity of the HXMoO3 nano-particle solution is improved. And the preparation of the HXMoO3 nano-particle solution with uniform particle size, uniform distribution, high conductivity of the film and high transmittance is realized. The HXMoO3 nanoparticle film prepared from the solution has excellent photoelectric properties and extremely high
