Halogenated dibenzoylmethane Eu<sup>3+</sup> complexes as spectroscopic markers: a pioneering photobleaching strategy for counterfeit applications and controlling luminescence efficiency
Enhancement of luminescence efficiency from 23% up to 64% by halogenation of ligands in Eu 3+ diketonate complexes was achieved. A novel type of luminescent taggant based on controlled photobleaching for anticounterfeiting application was created.
