AUTHENTICITY MARK IN THE FORM OF A LUMINESCENT SUBSTANCE |
| 摘要 |
The invention relates to a printed document of value having at least one authenticity feature in the form of a luminescent substance on the basis of host lattices which are doped with one or a plurality of ions. By suitably doping host lattices with different ions, exchange interactions between clusters of ions occur which can lead to cooperative effects.
