2. The security feature according to claim 1 , wherein the security feature has a production component, which is added to the security feature in a proportion for adjusting the signal intensity of the luminescence of the luminescent component to a specified nominal magnitude.

3. The security feature according to claim 2 , wherein the production component has at least one chemical element, the chemical element being a constituent of at least one other component of the security feature.

4. The security feature according to claim 2 , wherein the production component has at least two different chemical elements, the first of the two different chemical elements being a constituent of a first other component of the security feature, and the second of the two different chemical elements being a constituent of a second other component of the security feature.

5. The security feature according to claim 1 , wherein the security feature has a coding component, for forensically marking the security feature.

6. The security feature according to claim 5 , wherein the coding component has at least one chemical element, the chemical element being a constituent of at least one other component of the security feature.

7. The security feature according to claim 5 , wherein the coding component is formed by a luminophore that differs from the luminescent component, the coding component having at least one chemical element that is shared with the luminescent component.

8. The security feature according to claim 1 , wherein the X-ray diffractogram of the luminescent component and the X-ray diffractogram of the first substance of the camouflaging component are at least partially congruent, with at least one relevant peak position overlapping.

9. The security feature according to claim 8 , wherein at least two of the relevant peak positions overlap, and wherein the at least two overlapping peaks have at least 30% of the height of a main peak.

10. The security feature according to claim 8 , wherein the overlapping peaks are a main peak of luminescent component and first substance of the camouflaging component.

11. The security feature according to claim 1 , wherein the components and substances are formed by inorganic host lattices or matrices.

12. The security feature according to claim 1 , wherein the security feature contains 20% to 80% of the luminescent component, and that the security feature contains 20% to 80% of the camouflaging component, and that the security feature contains 0 to 30% of a production component, and that the security feature contains 0 to 10% of a coding component.

13. The security feature according to claim 1 , wherein the luminescing component and the camouflaging component moreover have the same or a similar density, with the deviation of the density of the camouflaging component from the density of the luminescent component amounting to less than 50%.

14. A value document having a security feature according to claim 1 , wherein the value document consists of paper and/or plastic.

15. The value document according to claim 14 , wherein the security feature is incorporated into the volume of the value document.

16. The value document according to claim 14 , wherein the security feature is printed to the value document as a coating.
