preparation example Construction

[0031] The embodiment of the present invention provides a method for preparing a perovskite quantum dot film, comprising the following steps:

[0032] S1. Prepare a coating liquid with a fluorine-containing polyolefin and a halide composition; the halide composition includes at least an inorganic halide and at least one organic halide;

[0033] S2, uniformly coating the prepared coating solution on the surface of the substrate to form a wet film coating;

[0034] S3, drying and curing.

[0035] Specifically, the coating solution in step S1 is prepared by the following steps:

[0036] S101. Add the fluorine-containing polyolefin into the first organic solvent according to the first preset mass ratio and stir until completely dissolved to obtain solution A;

[0037] S102. Prepare a halide composition with an inorganic halide and at least one organic halide in a second preset molar ratio;

[0038] adding the halide composition into the second organic solvent, heating and stirr...

Abstract

The invention discloses a preparation method of a perovskite quantum dot film. The preparation method comprises the following steps: preparing a coating liquid from fluorine-containing polyolefin and a halide composition, wherein the halide composition at least comprises an inorganic halide and at least one organic halide; uniformly coating the surface of a base material with the prepared coating liquid to form a wet film coating; and drying and curing the wet film coating. The preparation method disclosed by the invention is simple and feasible in process steps, especially does not need to adopt a vacuum drying process, greatly shortens a preparation process and reduces preparation cost, and is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of quantum dot optical films, in particular to a perovskite quantum dot film and a preparation method thereof. Background technique [0002] In recent years, the application of quantum dot materials in display devices has attracted more and more attention. With its unique narrow emission spectrum and high color saturation, it can significantly improve the color display range of display devices; especially the calcium Titanium quantum dots and luminous efficiency have shown advantages, and have become a star material in the field of display devices. [0003] The Chinese Patent Publication No. CN104861958A discloses a perovskite / polymer composite luminescent material and its preparation method, which realizes the in-situ preparation of perovskite quantum dots in a polymer matrix, and the resulting composite film has excellent Luminescent properties, however, the preparation method needs to adopt vacuum drying...
