Abstract

The invention discloses a quantum dot light-emitting layer, a quantum dot light-emitting device and a preparation method, and relates to the field of display technology. The quantum dot light-emitting layer includes: a metal organic framework layer, and quantum dots embedded in pores of the metal organic framework layer. The confinement and modification of quantum dots through the metal organic framework layer can not only avoid the self-quenching effect caused by the aggregation of quantum dots, but also help to improve their luminescent performance.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to a quantum dot light-emitting layer, a quantum dot light-emitting device and a preparation method. Background technique

[0002] Quantum dot light-emitting layers are widely used in quantum dot light-emitting devices based on their high color gamut, such as quantum dot light-emitting diodes. Therefore, it is very necessary to provide a quantum dot light-emitting layer.

[0003] In related technologies, quantum dots coated with ligands on the surface are dissolved in a solvent to obtain a quantum dot solution, and the quantum dot solution is deposited on a substrate or a functional layer by a solution method to obtain a quantum dot light-emitting layer.

[0004] However, during the preparation process, quantum dots are prone to agglomeration, which in turn causes quantum dots to self-quench. Contents of the invention

[0005] In view of this, the present invention provides a qu...
