  • Composite polymer/perovskite quantum dots luminescent material
    Patent number: 11312899
    Abstract: A composite luminescent material synthesized by forming a precursor solution, forming a perovskite quantum dot/polymer composite by transferring the precursor solution onto a first substrate, and forming a composite luminescent material by coating the perovskite quantum dot/polymer composite with a polydimethylsiloxane (PDMS) solution. An exemplary precursor solution may be formed by obtaining a first solution by dissolving a polymer in a first organic solvent, obtaining a second solution by mixing an inorganic metal halide solution and an organic amine halide solution, and mixing the first solution and the second solution.
    Type: Grant
    Filed: January 23, 2020
    Date of Patent: April 26, 2022
    Assignee: TARBIAT MODARES UNIVERSITY
