Document Type and Number:
WIPO Patent Application WO/2024/078624
Kind Code:
A1
Abstract:
A fluorescent composite particle, comprising a fluorescent material having a plurality of fluorescent nanocrystals, and an oxide material. The oxide material densely coats the fluorescent material, and the molar ratio of the fluorescent material to the oxide material is 10:1 to 1:100. The fluorescent composite particle has a particle size of 20 nm to 500 nm, a density of 1.8 g/cm3 to 7 g/cm3, and a specific surface area of 8 m2/g to 200 m2/g. The fluorescent composite particle has high stability and small particle size. Moreover, a preparation method for obtaining a fluorescent composite particle having a predetermined morphology is provided.
