  • Publication number: 20210040387
    Abstract: A method of preparing a quantum dot nanoparticle is disclosed. The method includes the step of reacting one or more cation precursors including one or more of Groups 12 and 13 elements with one or more anion precursors including one or more of Group 15 elements to prepare a quantum dot nanoparticle, wherein the reaction of the cation precursors and the anion precursors is carried out while supplying a compound represented by Chemical Formula 1. A quantum dot nanoparticle prepared by the preparation method, a quantum dot nanoparticle having a core-shell structure containing the quantum dot nanoparticle as a core, and a light emitting element comprising the quantum dot nanoparticle having a core-shell structure are also disclosed.

  • Publication number: 20210013382
    Abstract: A light conversion film is disclosed. The light conversion film includes a first transparent support layer and a second transparent support layer are formed on upper and lower surfaces of a quantum dot layer, respectively. The quantum dot layer contains 0.4 to 2.0% by weight of quantum dot particles containing 5% by weight or more and less than 35% by weight of cadmium; 0.05 to 0.75% by weight of cadmium-free quantum dot particles; 0.1 to 10% by weight of scattering agent; and 75 to 98% by weight of matrix material, based on the total weight of the quantum dot layer. A backlight unit for a display device including the light conversion film is disclosed.
