Definitions
- the invention relates to a sensor for the authenticity detection of a lumen-emitting security element of a value document, with an emitter for generating a scanning signal with an excitation wavelength, and with a radiation receiver for detecting a response signal emitted by the security element with a response wavelength. It further relates to a value document with at least one security element designed for authenticity detection by such a sensor, and to a method for producing such a value document.
- value or security documents such as banknotes, ID cards or chip cards
- security features or security elements which, for example in the case of paper-based value documents, are intended to reliably preclude imitation by making color copies.
- the security elements can in particular be designed as optically variable elements, such as holograms or interference layer elements, which convey different color impressions when viewed depending on the viewing angle, but are not transferred to the copy during the copying process.
- security elements of this type cannot be read out or evaluated by machine, or can only be carried out with difficulty, so that an automated security check of the respective value documents is only possible to a limited extent and with high technical outlay.
- a value document as a data carrier, such as an identification card, credit card, passport, driver's license or the like, in addition to a visually recognizable authenticity check, the possibility of a machine authenticity check with high security against forgery is of particular importance.

- a suitable sensor is used to irradiate a scanning signal generated by an emitter, in particular a laser, into the marking area in which the anti-Stokes pigments are kept.
- the anti-Stokes pigments in the so-called “up-conversion mode” emit a response signal with a shorter response wavelength than the excitation wavelength, which is recorded in a suitably designed radiation receiver.
- the excitability of the Anti-Stokes pigments depends on the irradiated excitation wavelength, the response wavelength emitted also being characteristic of the material properties of the anti-Stokes pigment used, in particular of its activator and codotation with regard to the host lattice used Response wavelength compared to the irradiated excitation wavelength, possibly with additional evaluation of the signal shape of the emitted response signal, is therefore a comparatively reliable assignment of the signature of the response signal to signatures expected for certain anti-Stokes pigments If the detected signature matches an expected signature, the expected presence of a certain group of anti-Stokes pigments and thus the authenticity of the value document provided with such a luminescent security mark can thus be concluded.
- the sensors known from EP 1170707 A2 and EP 1160719 A2 are particularly suitable for use in the detection of authenticity of documents of value with such luminescent security elements.
- Such sensors include an emitter for generating the scanning signal and a radiation receiver for detecting the response signal and can be designed to be static, stationary or mobile as a hand sensor.
- the invention is based on the object of developing a sensor of the type mentioned above in such a way that a particularly high detection sensitivity and accuracy can be achieved in the authenticity check of the value document. Furthermore, one should a value document that is particularly suitable for authenticity detection by such a sensor and a method for producing the value document can be specified.
- this object is achieved according to the invention in that the emitter is designed to generate the scanning signal with an excitation wavelength of approximately 940 nm to 990 nm and the radiation receiver is designed to detect the response signal with a response wavelength of approximately 800 +/- 10 nm.
- the invention is based on the consideration that for a particularly high detection sensitivity, the evaluation of the luminescent properties of the security element should be specifically aimed at a particularly high signal intensity of the anti-Stokes pigments that can be achieved.
- the type classes of anti-Stokes pigments that are particularly suitable for use in documents of value, it has surprisingly been found that the actually invisible anti-Stokes band located in the near infrared (NIR) range is particularly high , has about 100 to 500 times the luminescence intensity compared to the emission in the visible range.
- NIR near infrared

- the document of value in its entirety is specifically aligned for common use with the sensor for authenticity detection.
- a marking layer which comprises anti-Stokes pigments which can be excited by the excitation wavelength of the sensor and which emit in the luminescence response with the intended response wavelength.
- the marking layer should be covered by a cover layer in the manner of a hidden, encapsulated or protected version.

- the anti-Stokes pigments mentioned also have anti-Stokes bands in the visually visible range, in particular between 460 and 490 nm and between 630 and 670 nm and between 680 and 720 nm, which are, however, considerably less intensive than those for evaluation now Anti-Stokes luminescence envisaged in the NIR range.
- the security features created with such anti-Stokes pigments can be used in a very fine grain size distribution of a few micrometers in size and, depending on the degree of filling, are invisible to whitish in preferably internal printed structures.
- an anti-Stokes pigment can also be used internally in documents, it being only necessary to ensure that the surrounding layers are NIR-transparent for evaluation.
- Such anti-Stokes pigments can thus be arranged on the document of value completely invisible to the human eye in terms of printing technology or in terms of area or even the entire area.
- the anti-Stokes pigment advantageously has a ytterbium content of 0.05 ⁇ x ⁇ 0. 80, preferably 0.20 ⁇ x ⁇ 0.60, and a rare earth content of 0.0001 ⁇ y ⁇ 0.10, preferably 0.0001 ⁇ y ⁇ 0.05. Additional cations and / or anions can also be built into the host lattice in order to influence the anti-Stokes pigment's decay and decay characteristics. By a suitable choice of Concentrations can be achieved in particular that the decay time can be set in a range from 1 to 200 ⁇ s and in particular from 10 to 50 ⁇ s.
- the document of value is particularly suitable for printing production processes.
- the anti-Stokes pigment advantageously has an average particle size of less than 5 ⁇ m, in a particularly advantageous embodiment less than 3 ⁇ m, in particular less than 2 ⁇ m.
- the anti-Stokes pigments are advantageously incorporated in the form of small inorganic particles in a printing ink, the degree of filling being in the range from 1 to 30 percent by weight, advantageously in the range from 1 to 20 percent by weight and preferably in the range from 5 to 10 percent by weight is selected so that the graphic and in particular color design is not disrupted.
- the document of value can in particular be designed in the manner of a data carrier as a so-called ID card, passport, visa, driver's license, credit card, postage stamp, coupon, general stamp, banknote or the like, with a high degree of reliability being a authenticity check at speeds of up to 10 m / s is feasible.
- the security element with the luminescent anti-Stokes pigments is furthermore in a particularly advantageous embodiment in a form invisible to the human eye as machine-readable coding in the form of individual or constant codes in the form of bar codes, 2-D codes, number Number symbol elements or the like are attached in the data carrier, the authenticity detection being carried out with the sensor and its evaluation unit in such a way that the code by means of a secret algorithm arranged in the evaluation unit in the form of a software module or also preferably in the form of a electronic component and / or in an external evaluation unit in connection with another information element on the data carrier can be verified for authenticity, information elements such as magnetic strips, bar codes, EAN codes and the like printing codes or also contact and / or contactless chip cards or RFID elements in the form of ROM-S memory elements with unique IC serial numbers from For example, some 10 bit to 128 bit length are secured against counterfeiting and / or copying.
- the luminescence provided for evaluation in the NIR range can be used in a particularly favorable manner by laminating the marking layer comprising the luminescent anti-Stokes pigments into a surrounding layer system.
- the value document therefore advantageously comprises a carrier body which is designed as a base body for the formation of a value or ID card into which the marking layer is laminated.
- the marking layer is advantageously covered by a plurality of NIR-transparent cover layers to form a laminate body.
- the marking layer is advantageously formed by an extruded or injection-molded plastic body in which the anti-Stokes pigments are embedded in a matrix. At least one, preferably both, surfaces of the substrate or the core layer comprising the marking layer can be provided with a graphic design and optionally with an upper cover laminate and / or a lower cover laminate.

- a coating method such as brushing, spraying, spraying, coating, dipping, but preferably using a printing method, preferably using screen printing, intaglio printing, offset printing, statistical printing, screen printing or letterpress printing.
- the specifications of a lateral structure can be provided in the marking layer, so that when analyzing the luminescence phenomena, a distinction can be made between active and inactive areas in a spatially resolved manner.
- radiation absorbers are advantageously generated in lateral partial areas of the marking layer by selective irradiation with a laser, preferably with an ND ⁇ AG laser with a wavelength of 1064 nm.
- the laser radiation can in particular produce soot particles that absorb the emission radiation from the anti-Stokes phosphors, so that no emission from the outside is registered in these areas.
- the advantages achieved by the invention are, in particular, that a particularly high signal intensity can be achieved through the targeted use of the luminescence phenomena of the anti-Stokes pigments in the NIR range, so that the pigments can be reliably identified during the authenticity check even with only comparatively low pigment concentrations can be reached in the marking layer.
- the luminescence security feature is also largely invisible in the visible wavelength range, but can be activated and verified by means of infrared radiation, so that the authenticity check is particularly suitable for machine evaluation. Due to the hidden arrangement of the security element, a replica of the security element is therefore not conceivable or only at all with considerable effort.
- the targeted influencing of the response and decay behavior of the anti-Stokes luminescence also makes it possible to increase the available variety of anti-Stokes pigments very greatly, so that replication or counterfeiting are made considerably more difficult.
