| titleOfInvention | Preparation method of fluorescent photonic crystal |
| abstract | The invention relates to a preparation method of a fluorescent photonic crystal, wherein the fluorescent photonic crystal comprises monodisperse polystyrene microspheres and water-soluble semiconductor quantum dots, and is characterized in that the water-soluble semiconductor quantum dots are uniformly dispersed on the surfaces of the polystyrene microspheres through dendritic macromolecules. The polystyrene microsphere has an average particle size of 245-285 nm, and can emit green, yellow and red fluorescence under ultraviolet irradiation. And then printing the synthesized quantum dot hybrid polystyrene colloidal particle emulsion into a fluorescent photonic crystal two-dimensional code pattern by a microfluid printing technology. The invention also provides a preparation method of the fluorescent photonic crystal and a printing method of the two-dimensional code pattern. The fluorescent photonic crystal has the advantages of bright color, good fluorescence stability, simplicity, high efficiency and the like. |
