Abstract
The present invention relates to fluorescent dye loaded particles and the method of preparing thereof. The method includes steps of preparing the nanoparticles with layered structure having at least one interlayer space, expanding the at least one interlayer space to form at least one expanded interlayer space, introducing the dye molecules to the at least one expanded interlayer space, and covalently bonding the dye molecules with the layered structure. The present invention also relates to a film comprising such nanoparticles.
