"Polymetallic nano-wheels fluoresce (glow) and magnetics allowing temperature changes and control... polymetallics of lanthanide, 15 rare earths... specifically used europium, terbium and gadolinium...  controlling hydrolysis of lanthanide metal ions in presence of organic ligands obtain desired species... hydrolysis to breakdown lanthanides in bath containing tricine containing multiple arms of oxygen and hydrogen, meaning it can accommodate a large range of metals and help stabilize resulting clusters"
