Abstract

The invention discloses a fluorescent quantum dot micro-nano encapsulated composite material structure. The composite material structure comprises fluorescent quantum dots, a mesoporous particle material with a nano lattice structure, and a barrier layer, wherein the fluorescent quantum dots are distributed in the mesoporous particle material, and the barrier layer coats the external surface of the mesoporous particle material. The composite material structure can effectively retard the aggregation of the quantum dots, and the barrier layer coating the surface prevents the erosion of water and oxygen small molecules and improves the compatibility and stability of composite fluorescent particles, thereby greatly prolonging the service life of the fluorescent quantum dot micro-nano encapsulated composite material.
