Claim Text:
1. A security feature having a luminescent component having at least one luminophore consisting of at least one doped host lattice, and a component camouflaging the luminescent component, wherein the camouflaging component has chemical elements that have similar structure-chemical properties to the chemical elements of the luminescent component, wherein the chemical elements of the camouflaging component and the chemical elements of the luminescent component are formed by different chemical elements, wherein the camouflaging component contains at least two additional chemical elements that have similar structure-chemical properties to the chemical elements of the host lattice, and contains at least one additional chemical elements that have similar structure-chemical properties to the chemical elements of a dopant employed for doping the host lattice, wherein the camouflaging component contains at least one substance for camouflaging the chemical elements of the host lattice, and at least one substance for camouflaging the employed dopant.
