Time-resolved fluorescence beads, as a special type of functional microspheres, are polystyrene microspheres internally embedded with complexes of rare earth ions. The rare earth ions commonly used for internal embedding include Eu3+, Tb3+, Sm3+, and Dy3+. When these rare earth ions form complexes with certain ligands such as β-diketones and aromatic amines, they can absorb […]
