Title:
METHOD FOR PREPARING QUANTUM DOT COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/024379
Kind Code:
A1
Abstract:
The present application discloses a method for preparing a quantum dot article. The method comprises the steps of: (1) granulating a mixture comprising a first precursor and a plastic material to obtain a first precursor particle; (2) granulating a mixture comprising a second precursor and a plastic material to obtain a second precursor particle, wherein the second precursor comprises an X precursor; and the second precursor particle comprises X particles; and (3) molding a mixture comprising the first precursor particle, the second precursor particle and a plastic material to obtain the quantum dot composite material. According to the method, three precursors of a perovskite quantum dot are respectively pre-granulated by means of pre-distributed granulation, such that three components are separated from one another in space, the contact time of the three components during an extrusion process is greatly shortened, further growth of the perovskite quantum dot in a plastic molten state is further limited, and after the plasticization is completed, a high-quality quantum dot optical article can be obtained.
