AUTHENTICITY MARK IN THE FORM OF LUMINESCENT SUBSTANCES |
摘要 |
The invention relates to a printed document of value having an authenticity feature in the form of at least two luminescent substances on the basis of host lattices which are doped with one or a plurality of ions. By systematically changing the host lattices and/or ions of the (nd)3 electron configuration a specific setting of the luminescence properties of luminescent substances is possible, the combination of which permits a multiplicity of complex new authenticity features.
