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.
Claims10
A preservation method of a quantum dot, the method is consisting of the following steps:
- dispersing a quantum dot in a first solvent to obtain a first quantum dot mixed solution;
- mixing a preservative and the first quantum dot mixed solution to obtain a second quantum dot mixed solution;
- removing the first solvent in the second quantum dot mixed solution to obtain a quantum dot composition,
- wherein the quantum dot composition only includes the quantum dot and the preservative, wherein the preservative is a long-chain unsaturated compound, and based on a total weight of the quantum dot composition, a content of the quantum dot is 5 wt % to 80 wt %, and a content of the preservative is 20 wt % to 95 wt %;
- and
- sealing the quantum dot composition for preservation.
