  • Preservation method of quantum dot and quantum dot composition
    Patent number: 11142688
    Abstract: A preservation method of a quantum dot and a quantum dot composition are provided. The method includes the following steps. A quantum dot is mixed with a preservative to form a quantum dot composition, wherein the preservative is a long-chain unsaturated compound, and based on the total weight of the quantum dot composition, the content of the quantum dot is 5 wt % to 80 wt %, and the content of the preservative is 20 wt % to 95 wt %. The quantum dot composition is sealed for preservation.
