Quantum dot color film and preparation method thereof

Abstract

The invention discloses a quantum dot color film and a preparation method thereof, and the material of the quantum dot color film comprises a PAMAM dendrimer and oil phase quantum dots combined in thecavity of the PAMAM dendrimer. In the quantum dot color film provided by the invention, the PAMAM dendrimer can realize coating and dispersion of the oil phase quantum dots, so that the oil phase quantum dots can effectively isolate water and oxygen, and the quantum dot color film can maintain stable performance.

Description

technical field [0001] The invention relates to the field of quantum dots, in particular to a quantum dot color film and a preparation method thereof. Background technique [0002] Quantum dots are one of the best candidate materials for display and lighting. The development of related technologies to prepare quantum dot color films and apply them to the field of lighting has attracted much attention. [0003] The existing key technology for applying quantum dots to the preparation of color filters is to coat quantum dots with a thick layer of SiO 2 The inorganic shell layer and the silica shell layer can well isolate the quantum dots from water and oxygen, and the quantum dots wrapped with the silica shell layer are relatively stable after being prepared into a quantum dot color film. However, the process of encapsulating quantum dots with silicon dioxide is relatively complicated, and the single coating and monodispersity of quantum dots are not easy to control, so the ex...
