| abstract |
The invention discloses a quantum dot light-emitting layer, a quantum dot light-emitting device and a preparation method, and relates to the technical field of display. 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 metal organic framework layers can not only avoid the self-quenching effect caused by the agglomeration of quantum dots, but also help to improve their luminescence properties. |
