| 摘要 |
The invention concerns a value document comprising particulate agglomerates respectively containing at least two different homogeneous phases, wherein the first homogeneous phase is based on a luminescent substance emitting at a certain emission wavelength and the second homogeneous phase is based on a non-luminescent substance detectable by a spectroscopic method, and wherein upon an evaluation of measurement values that are obtainable by a location-specific measurement, carried out at different locations of the value document, of the luminescence intensity at the certain emission wavelength and the intensity of the measurement signal of the spectroscopic method, there is a statistical correlation between the luminescence intensity at the certain emission wavelength and the intensity of the measurement signal of the certain spectroscopic method. |
