Abstract
A composite material for fluorescent quantum dot micro-nano packaging. The composite material comprises fluorescent quantum dots, a mesoporous particle material having a nanometer lattice structure, and a barrier layer, wherein the fluorescent quantum dots are distributed in the mesoporous particle material, and the barrier layer is coated on the outer surface of the mesoporous particle material. In the composite material according to the invention, the quantum dot aggregation can be effectively retarded, with the barrier layer coated on the surface the water-oxygen micromolecule erosion is prevented, the compatibility and stability of the composite fluorescent particles is improved, and the service life of the composite material for fluorescent quantum dot micro-nano packaging is thus greatly improved.
