Abstract

A quantum dot film comprises a plurality of quantum dots having a metal atom and ligands allocated to the surface of the quantum dots; the quantum dots are mutually connected. The quantum dot film prepared via a preparation method of the invention has better electroluminescence. The invention also provides a solar battery, a light-emitting diode and a display device using the quantum dot film.

Description

technical field [0001] The invention relates to a quantum dot film for photoelectric or electro-optical conversion. The present invention also relates to solar cells, light emitting diodes and display devices constructed using the above-mentioned quantum dot film. Background technique [0002] Because quantum dots have the advantages of controllable particle size, uniform dispersion, high excitation conversion efficiency, stability, and high light efficiency, they have great application prospects in the fields of display devices and solar cells. In electro-optic conversion or photoelectric conversion devices, the construction of quantum dot film has always been a key step. At present, the quantum dot film is generally formed by spin-coating the quantum dot solution on the substrate and evaporating the solvent. Aiming at the problem of low electron transport in quantum dot films, currently ligands with better electron transport capabilities are mainly obtained through ligan...
